# MAX4233AUB+T

**Analog Devices Inc Maxim Integrated** · Operational Amplifier · MSOP-10

MAX4233AUB+T from Analog Devices Inc Maxim Integrated, in a MSOP-10. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTA | output | Op-amp A output. Rail-to-rail output stage capable of driving ~50mA into loads down to a few tens of ohms; swings within tens of mV of either supply rail with light loads. |
| 2 | INA- | input | Inverting input of op-amp A. High-impedance CMOS input; common-mode range extends rail-to-rail (V- to V+). |
| 3 | INA+ | input | Non-inverting input of op-amp A. High-impedance CMOS input; rail-to-rail common-mode range. |
| 4 | V+ | power_in | Positive supply rail. Operating range 2.7V to 5.5V referenced to V-/GND. Bypass with a 0.1µF ceramic capacitor to GND close to the pin. |
| 5 | SHDNA | input | Active-low shutdown for op-amp A. Drive low to disable amplifier A and place its output into a high-impedance state; drive high (or tie to V+) for normal operation. |
| 6 | SHDNB | input | Active-low shutdown for op-amp B. Drive low to disable amplifier B and place its output into a high-impedance state; drive high (or tie to V+) for normal operation. |
| 7 | INB+ | input | Non-inverting input of op-amp B. High-impedance CMOS input; rail-to-rail common-mode range. |
| 8 | INB- | input | Inverting input of op-amp B. High-impedance CMOS input; rail-to-rail common-mode range. |
| 9 | OUTB | output | Op-amp B output. Rail-to-rail output stage capable of driving ~50mA into loads down to a few tens of ohms; swings within tens of mV of either supply rail with light loads. |
| 10 | V- | power_in | Negative supply / ground. Tie to system ground for single-supply operation, or to the negative rail for split-supply operation. |
