# HT1188ARTZ

**HTCSEMI** · Operational Amplifier · SOT-23-5

HT1188ARTZ from HTCSEMI, in a SOT-23-5. 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 | OUT | output | Amplifier output. Rail-to-rail output; swings to within ~10mV typical of each supply rail. Output short-circuit current ~80mA; typical output drive 50mA. |
| 2 | GND | power_in | Ground / negative supply return. Connect to the most negative supply rail. All GND pads are connected on-die. |
| 3 | INP | input | Non-inverting analog input of the amplifier. Common-mode voltage range extends from 0V to VDD (beyond-the-rails input capability). Typical input bias current 1pA; input resistance >100GΩ. |
| 4 | INN | input | Inverting analog input of the amplifier. Same voltage range as INP (0V to VDD, rail-to-rail input). Typical input bias current 1pA. |
| 5 | VDD | power_in | Positive power supply pin. Operating range 2.5V to 5.5V (absolute maximum 6V). Quiescent current 150µA typical / 330µA max per amplifier. |
