MAX44244/MAX44245/ MAX44248


36V, Precision, Low-Power, 90μA,

Single/Quad/Dual Op Amps


General Description

The MAX44244/MAX44245/MAX44248 family of parts provide ultra-precision, low-noise, zero-drift single/quad/ dual operational amplifiers featuring very low-power operation with a wide supply range. The devices incorporate a patented auto-zero circuit that constantly measures and compensates the input offset to eliminate drift over time and temperature as well as the effect of 1/f noise. These devices also feature integrated EMI filters to reduce high-frequency signal demodulation on the output. The op amps operate from either a single 2.7V to 36V supply or dual ±1.35V to ±18V supply. The devices are unity-gain stable with a 1MHz gain-bandwidth product and a low 90µA supply current per amplifier.

The low offset and noise specifications and high supply range make the devices ideal for sensor interfaces and transmitters.

The devices are available in µMAX®, SO, SOT23, and TSSOP packages and are specified over the -40°C to

+125°C automotive operating temperature range.

Detailed Description

The MAX44244/MAX44245/MAX44248 are high-

precision amplifiers with less than 2µV (typ) input-referred offset and low input voltage-noise density at 10Hz. 1/f noise, in fact, is eliminated to improve the performance in low-frequency applications. These characteristics are achieved through an auto-zeroing technique that cancels the input offset voltage and 1/f noise of the amplifier.

External Noise Suppression in EMI Form These devices have input EMI filters to prevent effects of radio frequency interference on the output. The EMI

filters comprise passive devices that present significant higher impedance to higher frequency signals. See the EMIRR vs. Frequency graph in the Typical Operating Characteristics section for details.

High Supply Voltage Range

The devices feature 90µA current consumption per chan- nel and a voltage supply range from either 2.7V to 36V single supply or ±1.35V to ±18V split supply.

Applications Information

The devices feature ultra-high precision operational amplifiers with a high supply voltage range designed for load cell, medical instrumentation, and precision instrument applications.

4–20mA Current-Loop Communication Industrial environments typically have a large amount of broadcast electromagnetic interference (EMI) from high-

voltage transients and switching motors. This combined with long cables for sensor communication leads to high-voltage noise on communication lines. Current-Loop communication is resistant to this noise because the EMI induced current is low. This configuration also allows for low-power sensor applications to be powered from the communication lines.

The Typical Operating Circuit shows how the device can be used to make a current loop driver.


The circuit uses low-power components such as the MAX44244 op amp, the 16-bit MAX5216 DAC, and the high-precision 60µA-only MAX6033 reference. In this circuit, both the DAC and the reference are referred to the local ground. The MAX44244 op-amp inputs are capable of swinging to the negative supply (which is the local ground in this case). R3 acts as a current mirror with

RSENSE. Therefore, if RSENSE = 50Ω (i.e. 20mA will drop 1V) and if the current through R3 is 10μA when IOUT is 20mA (0.05% error) then R3 = 100kΩ. R1 is chosen along with the reference voltage to provide the 4mA offset. R2

= 512kΩ for 20mA full scale or R2 = 614kΩ for 20% over- range. RSENSE is ratiometric with R3, R1 independently sets the offset current and R2 independently sets the

DAC scaling.

Driving High-Performance ADCs

The MAX44244/MAX44245/MAX44248’s low input offset voltage and low noise make these amplifiers ideal for ADC buffering. Weight scale applications require a low- noise, precision amplifier in front of an ADC. Figure 1 details an example of a load cell and amplifier driven from the same 5V supply, along with a 16-bit delta sigma ADC such as the MAX11205.

The MAX11205 is an ultra-low-power (< 300μA, max active current), high-resolution, serial output ADC. It provides the highest resolution per unit power in the industry and is optimized for applications that require very

high dynamic range with low power such as sensors on a 4–20mA industrial control loop. The devices provide a high-accuracy internal oscillator that requires no external components.

Layout Guidelines

The MAX44244/MAX44245/MAX44248 feature ultra-low input offset voltage and noise. Therefore, to get optimum performance follow the layout guidelines.

Avoid temperature tradients at the junction of two dissimilar metals. The most common dissimilar metals used on a PCB are solder-to-component lead and solder-to-board trace. Dissimilar metals create a local thermocouple. A variation in temperature across the board can cause an additional offset due to Seebeck effect at the solder junctions. To minimize the Seebeck effect, place the amplifier away from potential heat sources on the board, if possible. Orient the resistors such that both the ends are heated equally. It is a good practice to match the input signal path to ensure that the type and number of thermoelectric juntions remain the same. For example, consider using dummy 0Ω resistors oriented in such a way that the thermoelectric source, due to the real resistors in the signal path, are cancelled. It is recommended to flood the PCB with ground plane. The ground plane ensures that heat is distributed uniformly reducing the potential offset voltage degradation due to Seebeck effect.
