HGSEMI · Operational Amplifier · MSOP-8

LM258AMM from HGSEMI, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 1OUT output Output of op-amp channel 1. Short-circuit protected; typical short-circuit output current ±24 mA (VCC=5V, VEE=-5V).
2 1IN- input Inverting input of op-amp channel 1. Input bias current typ. 50 nA, offset current typ. 10 nA.
3 1IN+ input Non-inverting input of op-amp channel 1. Common-mode input range VEE to (VCC-1.5V).
4 VEE power_in Negative supply / ground. Connect to GND for single-supply operation (VCC 3V-36V), or to a negative rail down to -18V for dual-supply operation.
5 2IN+ input Non-inverting input of op-amp channel 2. Common-mode input range VEE to (VCC-1.5V).
6 2IN- input Inverting input of op-amp channel 2. Input bias current typ. 50 nA, offset current typ. 10 nA.
7 2OUT output Output of op-amp channel 2. Short-circuit protected; typical short-circuit output current ±24 mA (VCC=5V, VEE=-5V).
8 VCC power_in Positive supply. Single-supply range 3V to 36V (VEE=GND), dual-supply range ±18V. Typical supply current 0.5 mA @ VCC=5V (no load).
