HT1062BNZ from HTCSEMI, in a DIP-16. 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 | power_in | Positive line terminal; the regulated line voltage VLN is typically 4.0 V at Iline = 15 mA, with absolute maximum continuous line voltage 12 V. |
| 2 | GAS1 | passive | Transmitting amplifier gain adjustment; R7 between GAS1 and GAS2 sets microphone gain between 44 dB and 52 dB, with C6 to SLPE and C8 to VEE for stability. |
| 3 | GAS2 | passive | Transmitting amplifier gain adjustment; R7 (68 k for typically 52 dB) is connected between GAS1 and GAS2. |
| 4 | QR | output | Non-inverting output of the receiving amplifier, with output impedance of about 4 ohms; R4 between GAR and QR sets the gain. |
| 5 | GAR | passive | Receiving amplifier gain adjustment; R4 between GAR and QR sets IR-to-QR gain between 20 dB and 31 dB (31 dB typical with R4 = 100 k). |
| 6 | MIC- | input | Inverting microphone input with 64 k differential input impedance (32 k single-ended to VEE) for dynamic, magnetic, piezo-electric or electret microphones. |
| 7 | MIC+ | input | Non-inverting microphone input with 64 k differential input impedance (32 k single-ended to VEE), typical gain 52 dB to LN with R7 = 68 k. |
| 8 | STAB | passive | Current stabilizer pin; a 3.6 k resistor from STAB to VEE sets the stabilizer current level. |
| 9 | VEE | power_in | Negative line terminal (ground reference, VEE = 0 V). |
| 10 | IR | input | Receiving amplifier input with about 21 k input impedance. |
| 11 | DTMF | input | Dual-tone multi-frequency input with about 20.7 k input impedance and typical gain to LN of 25.5 dB (R7 = 68 k), with confidence tone in the earpiece. |
| 12 | MUTE | input | Mute input, active HIGH on the HT1062B (HIGH level input at least 1.5 V up to VCC, LOW level at most 0.3 V), selecting DTMF versus microphone and receiving amplifier. |
| 13 | VCC | power_out | Positive supply decoupling pin that also supplies external circuits, with typical VCC of 2.2 V minimum at Iline = 15 mA and Ip = 1.2 mA (2.7 V typical at Ip = 0 mA) and internal supply current of 0.9 to 1.35 mA at VCC = 2.8 V. |
| 14 | REG | passive | Voltage regulator decoupling pin with a capacitor to VEE; RVA from REG to SLPE raises, and from LN to REG lowers, the DC line voltage. |
| 15 | AGC | input | Automatic gain control input; R6 to VEE sets line-loss compensation with a 5.8 dB control range, and the pin may be left open for no compensation. |
| 16 | SLPE | passive | Slope (DC resistance) adjustment pin; external resistor R9 (normally 20 ohms) between SLPE and VEE sets the DC slope of the line voltage. |
