Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTA | output | Amplifier A output. Rail-to-rail push-pull output; swings within ~5 mV of the supply rails into 100 kohm and within ~20 mV into 10 kohm. Short-circuit limited to ~20 mA typ (15 mA min) source/sink. |
| 2 | INA- | input | Amplifier A inverting input. High-impedance CMOS input with rail-to-rail common-mode range (Vss-0.1 V to Vdd+0.1 V). Typical input bias current 20 pA. |
| 3 | INA+ | input | Amplifier A non-inverting input. High-impedance CMOS input with rail-to-rail common-mode range (Vss-0.1 V to Vdd+0.1 V). Typical input bias current 20 pA. |
| 4 | VSS | power_in | Negative supply / ground. Single-supply operation ties this to GND; dual-supply operation ties this to the negative rail. Bypass with 0.1 uF close to the pin in dual-supply designs. Absolute maximum Vdd-Vss = 7.5 V. |
| 5 | INB+ | input | Amplifier B non-inverting input. High-impedance CMOS input with rail-to-rail common-mode range (Vss-0.1 V to Vdd+0.1 V). Typical input bias current 20 pA. |
| 6 | INB- | input | Amplifier B inverting input. High-impedance CMOS input with rail-to-rail common-mode range (Vss-0.1 V to Vdd+0.1 V). Typical input bias current 20 pA. |
| 7 | OUTB | output | Amplifier B output. Rail-to-rail push-pull output; swings within ~5 mV of the supply rails into 100 kohm and within ~20 mV into 10 kohm. Short-circuit limited to ~20 mA typ (15 mA min) source/sink. |
| 8 | VDD | power_in | Positive supply. Single-supply range +1.8 V to +5.5 V (dual-supply +/-0.9 V to +/-2.75 V). Bypass with a 0.1 uF ceramic close to the pin. Absolute maximum Vdd-Vss = 7.5 V. |
