CBM2902ATS14

Corebai Microelectronics · Operational Amplifier · TSSOP-14

CBM2902ATS14 from Corebai Microelectronics, in a TSSOP-14. 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 OUT1 output Amplifier 1 output, with swing from 0 V to VCC-1.5 V and continuous short-circuit capability.
2 IN1(-) input Amplifier 1 inverting input, with common-mode range including ground and an absolute maximum input range of -0.3 V to 32 V.
3 IN1(+) input Amplifier 1 non-inverting input, with common-mode range including ground and an absolute maximum input range of -0.3 V to 32 V.
4 VCC power_in Positive supply pin, operating range 3 V to 32 V single supply (or ±1.5 V to ±16 V split) with an absolute maximum of 32 V.
5 IN2(+) input Amplifier 2 non-inverting input, with common-mode range including ground and an absolute maximum input range of -0.3 V to 32 V.
6 IN2(-) input Amplifier 2 inverting input, with common-mode range including ground and an absolute maximum input range of -0.3 V to 32 V.
7 OUT2 output Amplifier 2 output, with swing from 0 V to VCC-1.5 V and continuous short-circuit capability.
8 OUT3 output Amplifier 3 output, with swing from 0 V to VCC-1.5 V and continuous short-circuit capability.
9 IN3(-) input Amplifier 3 inverting input, with common-mode range including ground and an absolute maximum input range of -0.3 V to 32 V.
10 IN3(+) input Amplifier 3 non-inverting input, with common-mode range including ground and an absolute maximum input range of -0.3 V to 32 V.
11 GND power_in Ground (negative supply) pin, which is the reference for the input and output voltage limits GND ≤ VIN or VOUT ≤ VCC.
12 IN4(+) input Amplifier 4 non-inverting input, with common-mode range including ground and an absolute maximum input range of -0.3 V to 32 V.
13 IN4(-) input Amplifier 4 inverting input, with common-mode range including ground and an absolute maximum input range of -0.3 V to 32 V.
14 OUT4 output Amplifier 4 output, with swing from 0 V to VCC-1.5 V and continuous short-circuit capability.
