LTC2053CMS8#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 (CLK on the LTC2053-SYNC); the datasheet gives VIL 0.5V max and VIH 2.5V min at a 3V supply, and VIH 4.5V min at a 5V supply, with shutdown supply current of 10µA max when VEN is at or above 2.5V (3V supply) or 4.5V (5V supply).
2	-IN	input	Inverting differential input; the differential input voltage is limited so that
3	+IN	input	Noninverting differential input; the differential input voltage is limited so that
4	V-	power_in	Negative supply; a 0.1µF ceramic bypass capacitor must 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; the input voltage range requires V- ≤ (V+IN - V-IN) + VREF ≤ V+ - 1.3V.
6	RG	input	Inverting input of the internal zero-drift op amp, used with two external resistors to set the DC gain as 1 + R2/R1.
7	OUT	output	Amplifier output, which swings rail-to-rail referenced to V-, with a 20mV maximum output voltage swing low.
8	V+	power_in	Positive supply; the LTC2053 operates from 2.7V to ±5.5V, with total supply voltage (V+ to V-) absolute maximum of 11V.
