# OP07CRZ

**HTCSEMI** · Operational Amplifier · SOP-8

OP07CRZ from HTCSEMI, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Offset Null 1 | passive | Offset null trim pin 1. Connect a 20kΩ potentiometer between Offset Null 1 (pin 1) and Offset Null 2 (pin 8) with the wiper tied to VCC+ to trim the input offset voltage to zero. |
| 2 | Inverting Input | input | Inverting (-) analog input of the op-amp. Differential input voltage rating ±30V; common-mode input range typically ±13.5V with ±15V supplies. Differential input resistance 33MΩ. |
| 3 | Non-inverting Input | input | Non-inverting (+) analog input of the op-amp. Input bias current 1.8nA typical, common-mode input resistance 120GΩ, common-mode rejection 120dB typical. |
| 4 | VCC- | power_in | Negative supply pin. Operates from ±3V to ±22V split supplies (absolute maximum ±22V). Tie to ground for single-supply operation where the input range permits. |
| 5 | N.C. | unconnected | No internal connection. Leave floating or optionally tie to ground; do not use as a signal tie-point. |
| 6 | Output | output | Op-amp output. Typical output swing ±13V into RL=10kΩ with ±15V supplies, open-loop output resistance 60Ω, slew rate 0.17V/µs, gain-bandwidth product 0.5MHz. |
| 7 | VCC+ | power_in | Positive supply pin. Operates from ±3V to ±22V split supplies (absolute maximum ±22V). Typical supply current 2.7mA (no load) at ±15V. |
| 8 | Offset Null 2 | passive | Offset null trim pin 2. Used with Offset Null 1 (pin 1) via a 20kΩ potentiometer whose wiper connects to VCC+ to null the input offset voltage. |

## CAD (KiCad official)

- Symbol: `OP07CRZ`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOP-8 (KiCad packages3D, STEP)
- 3D model files: `op07crz-etched.step` / `op07crz-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `op07crz.step` / `op07crz.glb` are the bare package body.
