JAJSGG7B January 2019 – August 2019 OPA1671
PRODUCTION DATA.
The OPA1671 features true rail-to-rail inputs, allowing full common mode operation from the negative supply voltage to the positive supply voltage. This full common mode operation is achieved with complimentary N-channel and P-channel differential input pairs. The N-channel pair is active for input voltages close to the positive rail, typically (V+) – 1.25 V to (V+) The P-channel is active for common-mode inputs from (V–) to (V+) – 1.25 V. There is a small transition region, typically from (V+) – 1.25 V to (V+) – 1 V. In this region, the offset voltage transitions between the P-channel and N-channel offset values. Figure 5 shows the difference between offset in the P and N regions.
