LM4890MM-JSM

JSMSEMI · Audio Amplifiers · MSOP-8

LM4890MM-JSM from JSMSEMI, 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 SD input Shutdown input: logic high (VSDIH min 1.2 V) runs the amplifier normally and logic low (VSDIL max 0.4 V) stops it into the low-power shutdown mode.
2 BYP passive Internal common-mode (half-supply) voltage node that requires an external bypass capacitor for filtering; the datasheet's recommended selection is given in its application section.
3 +IN input Non-inverting analog input of the amplifier.
4 -IN input Inverting analog input whose closed-loop gain is set by the external input resistor RIN and feedback resistor Rf.
5 VO- output Negative analog output of the bridge-tied-load (BTL) output stage, driving the load together with VO+.
6 VDD power_in Positive power supply input; the operating range is 2.2 V to 5.5 V and the absolute maximum supply voltage is 5.5 V.
7 GND power_in Negative power supply input and the reference for all voltages measured in the datasheet.
8 VO+ output Positive analog output of the bridge-tied-load (BTL) output stage, driving the load together with VO-.
