LTC1992IMS8#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 | -IN | input | Inverting amplifier input connected to the P-channel MOSFET input device on the LTC1992, with a nominal 30k input resistor on LTC1992-1/-2/-5 and 15k on LTC1992-10 (the -X variants only). |
| 2 | VOCM | input | Output common mode voltage set pin, a high impedance input that must be connected to a known and controlled voltage and must never be left floating, with output common mode range of (-VS) + 0.5V to (+VS) - 1.3V. |
| 3 | +VS | power_in | Positive supply pin, specified from 2.7V to 11V, to be bypassed with a 0.1μF capacitor placed as close as possible to the pin. |
| 4 | +OUT | output | Positive rail-to-rail amplifier output designed to drive capacitive loads up to 10,000pF and sourcing or sinking 10mA (min). |
| 5 | -OUT | output | Negative rail-to-rail amplifier output designed to drive capacitive loads up to 10,000pF and sourcing or sinking 10mA (min). |
| 6 | -VS | power_in | Negative supply pin (ground in single-supply use), to be bypassed with a 0.1μF capacitor placed as close as possible to the pin. |
| 7 | VMID | passive | Mid-supply reference from an on-chip resistive divider; if used, short it to pin 2 and bypass with 0.1μF to ground, otherwise leave it floating. |
| 8 | +IN | input | Noninverting amplifier input connected to the P-channel MOSFET input device on the LTC1992, with a nominal 30k input resistor on LTC1992-1/-2/-5 and 15k on LTC1992-10 (the -X variants only). |
