The LT®1464 (dual) and LT1465 (quad) are the first micropower op amps (200A max per amp) to offer picoampere input bias currents (500fA typ) and unity-gain stability for capacitive loads up to 10nF. The output can swing a 10k load to within 1.5V of either supply, just like op amps that require an order of magnitude more supply current. This unique combination of performance makes the LT1464/LT1465 ideal over a wide range of input and output impedances.
In the design and testing of the LT1464/LT1465, particular emphasis has been placed on optimizing performance in the low cost SO-8 (dual) and 14-lead SO (quad) package for
15V and 5V supplies. The input common mode range
includes the positive rail. Slew rate (0.5V/s min) and gain bandwidth product (650kHz min) are 100% tested. A full set of matching specifications is also provided.

The ●denotes specifications which apply over the full operating temperature range.
Note 2: The LT1464 and LT1465 are designed, characterized and expected to meet these extended temperature limits, but are not tested at – 40C and 85C. Guaranteed I grade parts are available, consult factory.
Note 3: Current noise is calculated from the formula: in = (2qib)1/2 where q = (1.6)(10)–19 coulomb. The noise of source resistors up to 1G swamps the contribution of current noise.
Note 4: Slew rate is measured in AV = –1; input signal is 7.5V, output is measured at 2.5V.
Note 5: CMRR and PSRR are defined as follows:
CMRR and PSRR are measured in V/V on the individual amplifiers.
The difference is calculated between the matching sides in V/V.
The result is converted to dB.

Most industry standard JFET input single, dual and quad op amps exhibit phase reversal at the output when the negative common mode limit at the input is exceeded. Commonmoderangeisatapremiumat5Vsupplies. The Figures show a 5.2V sine wave input (Figure 1a), the response of a competing JFET input op amp in the unity-
gain follower mode (Figure 1b) and the response of the LT1464/LT1465 (Figure 1c).
The phase reversal of Figure 1b can cause lock-up in servo systems. The LT1464/LT1465 does not phase-reverse when the common mode input is anywhere within the supplies.
