LTC2053IMS8#TRPBF from Analog Devices, in a MSOP-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 | EN | input | Active-low enable pin on the LTC2053; the datasheet gives shutdown supply current of 10µA with VEN ≥ 2.5V at 3V supply and VEN ≥ 4.5V at 5V supply. |
| 2 | -IN | input | Inverting input of the differential amplifier; the datasheet limits |V-IN - VREF| to 5.5V. |
| 3 | +IN | input | Noninverting input of the differential amplifier; the datasheet limits |V+IN - VREF| to 5.5V. |
| 4 | V- | power_in | Negative supply; a 0.1µF ceramic bypass capacitor should be connected between pin 8 (V+) and pin 4 (V-) with leads as short as possible. |
| 5 | REF | input | Voltage reference (VREF) for the amplifier output, which sets the output level. |
| 6 | RG | input | Inverting input of the internal zero-drift op amp, used with external resistors to program the DC gain (see Figure 1). |
| 7 | OUT | output | Amplifier output, which swings rail-to-rail referenced to V-; see Figure 1. |
| 8 | V+ | power_in | Positive supply; the datasheet specifies single supply from 2.7V and dual supplies up to ±5.5V. |
