TEA1110AG-S14-R from UTC(Unisonic Tech), in a SOP-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 | LN | passive | Positive line terminal; DC line voltage is 3.65V typ at ILINE=15mA, absolute max continuous VEE-0.4 to 12V. |
| 2 | SLPE | passive | Slope (DC resistance) adjustment pin where an external RSLPE (20Ω recommended) sets the DC characteristics. |
| 3 | REG | passive | Line voltage regulator decoupling pin with CREG (4.7µF) to VEE; an RVA resistor to SLPE or LN adjusts VREF from 3.35V. |
| 4 | NC | unconnected | Not connected. |
| 5 | DTMF | input | Dual-tone multi-frequency input, asymmetrical with 20kΩ impedance to VEE, active when MUTE is low and unaffected by AGC. |
| 6 | MUTE | input | Active-low mute input selecting speech or dialling mode, with internal pull-up resistor; low level VEE-0.4 to VEE+0.3V, high level VEE+1.5V to VCC+0.4V. |
| 7 | IR | input | Receiving amplifier input with 20kΩ input impedance to VEE. |
| 8 | AGC | input | Automatic gain control/line loss compensation pin; RAGC to VEE shifts ISTART and ISTOP, and AGC is inactive when open-circuit. |
| 9 | MIC- | input | Inverting microphone amplifier input, with 64kΩ differential impedance between MIC+ and MIC-. |
| 10 | MIC+ | input | Non-inverting microphone amplifier input, with 64kΩ differential impedance between MIC+ and MIC-. |
| 11 | VEE | power_in | Negative line terminal (ground reference, 0V). |
| 12 | QR | output | Earpiece amplifier output, with 33dB typical gain from IR. |
| 13 | GAR | passive | Earpiece amplifier gain adjustment pin; an external resistor to QR reduces gain by up to 14dB. |
| 14 | VCC | power_out | Supply voltage for internal circuit and peripheral circuits, typically 2.9V at IP=0mA, decoupled by CVCC (100µF). |
