The OP271 is a unity-gain stable monolithic dual op amp
16-Pin SOL
featuring excellent speed, 8.5 V/ms typical, and fast settling
(S-Suffix)
time, 2 ms typical to 0. 01%. The OP271 has a gain bandwidth of 5 MHz with a high phase margin of 62∞. Input offset voltage of the OP271 is under 200 mV with input
OUT A 1 8 V+ A
offset voltage drift below 2 mV/∞C, guaranteed over the full
–IN A B 2 7 OUT B – + + –
military temperature range. Open-loop gain exceeds 400,000
+IN A 3 6 –IN B
into a 10 kW load ensuring outstanding gain accuracy and
V– 4 5 +IN B
linearity. The input bias current is under 20 nA limiting errors due to source resistance. The OP271’s outstanding
Epoxy Mini-DIP
CMR, over 106 dB, and low PSRR, under 5.6 mV/V, reduce
(P-Suffix)
errors caused by ground noise and power supply fluctuations.
8-Pin Hermetic DIP
In addition, the OP27l exhibits high CMR and PSRR over a
(Z-Suffix)
wide frequency range, further improving system accuracy.
