Texas Instruments · Operational amplifier · SOIC-8
High-speed op-amp with a FET input, so it combines a 140 MHz gain-bandwidth and fast slew rate with the femtoamp-class bias current of a CMOS part. That pairing suits it to transimpedance stages for photodiodes and to buffering high-impedance sensors at speed, where a bipolar high-speed amp would load the source. A rail-to-rail output and a wide 4.75 to 27 V supply give plenty of headroom. A fast, high-input-impedance workhorse for instrumentation.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No internal connection. Leave floating or tie to a quiet plane; do not connect to signal or supply nets. |
| 2 | VIN- | input | Inverting input pin of the op-amp. FET-input stage with typical 2pA input bias current; allowable differential input voltage ±7V. Common-mode input impedance ~12GΩ |
| 3 | VIN+ | input | Noninverting input pin of the op-amp. Rail-to-rail FET input with 2pA typical bias current; input voltage range extends to V(S-)-0.2V and V(S+)+0.2V. |
| 4 | VS- | power_in | Negative power-supply pin. Total supply voltage V(S+)-V(S-) between 4.75V and 27V (max ±14V bipolar). Bypass with decoupling capacitors close to the pin. |
| 5 | NC | unconnected | No internal connection. Leave floating or tie to a quiet plane; do not connect to signal or supply nets. |
| 6 | VO | output | Amplifier output pin. Rail-to-rail output with 75mA typical high linear output current; short-circuit current ~100mA; drives up to 10pF capacitive load with <3dB peaking (Rs=0Ω). |
| 7 | VS+ | power_in | Positive power-supply pin. Total supply voltage V(S+)-V(S-) between 4.75V and 27V (max ±14V bipolar). Quiescent current 3.7mA/channel (typ). Bypass close to pin. |
| 8 | NC | unconnected | No internal connection. Leave floating or tie to a quiet plane; do not connect to signal or supply nets. |
