OPA4197IPWR

Tokmas · Operational Amplifier · TSSOP-14

OPA4197IPWR from Tokmas, 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 OUTA output Amplifier A output.
2 -INA input Amplifier A inverting input; voltage range is from VS- to VS+ - 1.5 V.
3 +INA input Amplifier A non-inverting input; same voltage range as -IN (VS- to VS+ - 1.5 V).
4 +VS power_in Positive power supply, 4.5 V to 48 V between VS+ and VS-; split supplies are possible.
5 +INB input Amplifier B non-inverting input; same voltage range as -IN (VS- to VS+ - 1.5 V).
6 -INB input Amplifier B inverting input; voltage range is from VS- to VS+ - 1.5 V.
7 OUTB output Amplifier B output.
8 OUTC output Amplifier C output.
9 -INC input Amplifier C inverting input; voltage range is from VS- to VS+ - 1.5 V.
10 +INC input Amplifier C non-inverting input; same voltage range as -IN (VS- to VS+ - 1.5 V).
11 -VS power_in Negative power supply, normally ground; may be tied to another voltage as long as VS+ to VS- is 4.5 V to 48 V.
12 +IND input Amplifier D non-inverting input; same voltage range as -IN (VS- to VS+ - 1.5 V).
13 -IND input Amplifier D inverting input; voltage range is from VS- to VS+ - 1.5 V.
14 OUTD output Amplifier D output.
