TC2018

Shenzhen Fuman · Audio Amplifiers · ESOP-8-EP

TC2018 from Shenzhen Fuman, in a ESOP-8-EP. 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 control: high level shuts the amplifier down, low level enables operation, and the pin floats low through an internal pull-down; VIH is 1.4 V minimum and VIL is 0.35 V maximum at VDD=5 V.
2 BYP passive Reference voltage (bias) pin whose bypass capacitor Cbyp sets start-up speed and affects noise, PSRR and turn-on/turn-off pop; the datasheet gives start-up time of 150 ms with Cbyp=1 µF.
3 MODE input AB/D class select: high level selects Class D, low level or floating selects Class AB; VIH is 1.4 V minimum and VIL is 0.35 V maximum.
4 IN input Audio inverting input; the gain is set by the external input resistor Ri, with the gain kept below 2 V/V for best performance.
5 VON output Negative audio output (BTL bridge output), driving the load together with VOP.
6 VDD power_in Positive power supply, specified from 2.5 V to 5.5 V with an absolute maximum of 5.5 V, decoupled with at least 2.2 µF low-impedance ceramic capacitor placed close to the pin.
7 GND power_in Power supply ground.
8 VOP output Positive audio output (BTL bridge output), driving the load together with VON.
9 GND power_in Ground connection to the chip's bottom heat sink (exposed thermal pad), which the datasheet lists as pin 9 for heat dissipation.
