The denotes specifications which apply over the full operating temperature range.

Note 1: Typical parameters are defined as 60% yield of parameter distributions of individual amplifiers, i.e., out of 100 LT1465s (or 100 LT1464s) typically 240 op amps (or 120) will be better than the indicated specification.

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:

  1. CMRR and PSRR are measured in V/V on the individual amplifiers.

  2. The difference is calculated between the matching sides in V/V.

  3. The result is converted to dB.

Note 6: This parameter is not 100% tested.

Note 7: Matching parameters are the difference between amplifiers A and D and between B and C on the LT1465; between the two amplifiers on the LT1464.

APPLICATIO S I FOR ATIO

Phase Reversal Protection

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.
