# TLE2021IDR

**Texas Instruments** · Precision Op Amps · SOIC-8

TLE2021IDR 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 | OFFSET N1 | passive | External input offset voltage adjustment terminal for trimming the input offset voltage of the amplifier. |
| 2 | -IN | input | Inverting input of the amplifier; differential input voltage is limited to about ±600 mV without external limiting resistance, and input current to ±1 mA per input. |
| 3 | +IN | input | Noninverting input of the amplifier; the common-mode input range includes the negative rail, which supports single-supply operation. |
| 4 | VCC- | power_in | Negative (lowest) power supply; operates as ±2 V to ±20 V dual supply or 4 V to 40 V single supply (VCC = VCC+ minus VCC-). |
| 5 | OFFSET N2 | passive | External input offset voltage adjustment terminal for trimming the input offset voltage of the amplifier; pin number taken from Figure 5-1, as Table 5-1 lists it as pin 2. |
| 6 | OUT | output | Amplifier output; output current is limited to ±20 mA per output for the TLE2021 and the output must not be shorted to VCC+. |
| 7 | VCC+ | power_in | Positive (highest) power supply; the total current into VCC+ is limited to 80 mA. |
| 8 | NC | unconnected | No internal connection; leave unconnected. |
