MAX9813HEKA+T

Maxim Integrated · Audio Power OpAmps · SOT-23-8

MAX9813HEKA+T from Maxim Integrated, in a SOT-23-8. 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 OUT output Rail-to-rail amplifier output that typically swings to within 100mV of the rails when driving 10kΩ and goes high-impedance in shutdown.
2 GND power_in Ground reference; all voltages are referenced to GND.
3 SHDN input Active-low shutdown input: connect to VCC for normal operation and to GND for shutdown, and do not leave unconnected because it is a high-impedance input.
4 IN1/IN2 input Input selector: driving high selects IN1 and driving low selects IN2, with logic high ≥2V and logic low ≤0.8V.
5 IN2 input Amplifier input 2 of the dual-input device, with a typical input impedance of 85kΩ.
6 IN1 input Amplifier input 1 of the dual-input device, with a typical input impedance of 85kΩ.
7 BIAS power_out Low-noise microphone bias output regulated to 2.3V for the L version and 4V for the H version, sourcing up to 2mA in the dual-input version.
8 VCC power_in Positive supply, 4.5V to 5.5V for the H version (2.7V to 3.6V for the L version), to be bypassed to GND with a 0.1µF capacitor.

  • Footprint: Package_TO_SOT_SMD:SOT-23-8
  • 3D model: SOT-23-8 (KiCad packages3D, STEP)
  • 3D model files: max9813heka-t-etched.step / max9813heka-t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); max9813heka-t.step / max9813heka-t.glb are the bare package body.
