# TSH122ICT

**STMicroelectronics** · Operational Amplifier · SOT-363-6

TSH122ICT from STMicroelectronics, in a SOT-363-6. 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 | IN | input | Analog video input to the internal voltage-feedback amplifier. An internal DC-shift lets the video signal reach close to 0 V; the amplifier applies an internal gain of ~6 dB (×2) toward the output. Input amplitude must remain within 0 V to Vcc. |
| 2 | GND | power_in | Device ground / 0 V reference. All voltages (except the differential input) are referenced to this pin. |
| 3 | SAG | output | SAG-correction pin used to compensate the low-frequency droop introduced by an AC-coupling capacitor on the output video line. Connects to the external SAG-correction network (series capacitor / resistor to the load coupling capacitor) so the buffer can restore the low-frequency response of the 75 Ω video path. |
| 4 | OUT | output | Rail-to-rail buffered video output intended to drive a 75 Ω video load. Typical output short-circuit current 75 mA; VOH ≈ 3.2 V at Vcc = 3.3 V, VOL ≈ 11 mV (RL = 150 Ω). |
| 5 | EN | input | Enable / power-down control input. Logic-high (≥ +0.7 V, up to Vcc) enables the TSH122; logic-low (0 to +0.3 V) forces power-down mode (typ. 4 nA, max 500 nA). Ton/Toff ≈ 1 µs. |
| 6 | Vcc | power_in | Positive single-supply input, 2.25 V to 5 V (production tested at 2.5 V and 3.3 V; absolute max 5.5 V). Typical DC consumption 1.7 mA at 2.5 V, 2 mA at 3.3 V. |

## CAD (KiCad official)

- Symbol: `TSH122ICT`
- Footprint: `Package_TO_SOT_SMD:SOT-363_SC-70-6`
- 3D model: SOT-363-6 (KiCad packages3D, STEP)
- 3D model files: `tsh122ict-etched.step` / `tsh122ict-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tsh122ict.step` / `tsh122ict.glb` are the bare package body.
