TS472IQT

STMicroelectronics · Audio Amplifiers · QFN-24(4x4)

TS472IQT from STMicroelectronics, in a QFN-24(4x4). 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 NC unconnected Not connected, floating pin.
2 BYP passive Bypass pin for external half-supply filtering capacitor (typically 1 μF) to stabilize internal bias voltage.
3 NC unconnected Not connected, floating pin.
4 GND power_in Ground reference.
5 IN- input Negative differential input to microphone preamplifier with 80-120 kΩ input impedance.
6 NC unconnected Not connected, floating pin.
7 NC unconnected Not connected, floating pin.
8 IN+ input Positive differential input to microphone preamplifier with 80-120 kΩ input impedance.
9 GS input Gain select input; connect external resistor (0 to 470 kΩ) to GND for adjustable gain from -1.5 to 41 dB, or apply voltage ≥1 V for 20 dB gain.
10 BIAS output Microphone bias voltage output typically 2.0 V at no load with 100 Ω output resistance, can source 2 mA maximum.
11 NC unconnected Not connected, floating pin.
12 NC unconnected Not connected, floating pin.
13 NC unconnected Not connected, floating pin.
14 C1 passive Low-pass filter capacitor connection (0-220 pF) to reduce output high-frequency cutoff from 40 kHz to desired frequency.
15 C2 passive Low-pass filter capacitor connection (0-220 pF) to reduce output high-frequency cutoff from 40 kHz to desired frequency.
16 OUT- output Negative differential output from microphone preamplifier with adjustable gain -1.5 to 41 dB.
17 OUT+ output Positive differential output from microphone preamplifier with adjustable gain -1.5 to 41 dB.
18 NC unconnected Not connected, floating pin.
19 NC unconnected Not connected, floating pin.
20 VCC power_in Power supply input, operating range 2.2 to 5.5 V single supply.
21 STBY input Standby control input; device ON when 1.5 ≤ VSTBY ≤ VCC, device OFF when 0 ≤ VSTBY ≤ 0.4 V.
22 GND power_in Ground reference.
23 NC unconnected Not connected, floating pin.
24 NC unconnected Not connected, floating pin.
25 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
