# TL026CD

**Texas Instruments** · Operational Amplifier · SOIC-8

TL026CD from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN- | input | Inverting differential input with an input resistance of 10 to 30 kΩ at AGC, IN+ or IN-, and a common-mode input voltage range of ±1 V. |
| 2 | REF OUT | output | Reference voltage output that provides Vref of 1.3 to 1.5 V over an output current range of −1 mA to 100 µA, and serves as the dc reference for the AGC bias. |
| 3 | VCC+ | power_in | Positive supply voltage with a recommended range of 3 V to 8 V (6 V nominal) and an absolute maximum of 8 V. |
| 4 | OUT- | output | Inverting differential output (emitter-follower) with output resistance of 20 Ω, a maximum peak-to-peak swing of 3 V into a 2 kΩ load, and output current limited to ±10 mA absolute maximum. |
| 5 | OUT+ | output | Non-inverting differential output (emitter-follower) with output resistance of 20 Ω, a maximum peak-to-peak swing of 3 V into a 2 kΩ load, and output current limited to ±10 mA absolute maximum. |
| 6 | VCC- | power_in | Negative supply voltage with a recommended range of −3 V to −8 V (−6 V nominal) and an absolute maximum of −8 V. |
| 7 | AGC | input | Gain-control input where gain falls from maximum to minimum as VAGC moves about 180 mV above or below Vref, with an input resistance of 10 to 30 kΩ. |
| 8 | IN+ | input | Non-inverting differential input with an input resistance of 10 to 30 kΩ at AGC, IN+ or IN-, and a common-mode input voltage range of ±1 V. |
