Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT A | output | Output of amplifier A. Rail-to-rail output; typical short-circuit current ~55 mA. Output swings within ~8 mV (10 kohm load) / ~25 mV (2 kohm load) of the supply rails. |
| 2 | -IN A | input | Inverting input of amplifier A. Rail-to-rail input, common-mode range -0.1 V to (V+)+0.1 V. Input bias current ~1 pA typical. |
| 3 | +IN A | input | Non-inverting input of amplifier A. Rail-to-rail input, common-mode range -0.1 V to (V+)+0.1 V. Input bias current ~1 pA typical. |
| 4 | V+ | power_in | Positive supply pin, shared by all four amplifiers. Operating range +2.5 V to +5.5 V (absolute max V+ to V- = 7.0 V). Place a 0.1 uF bypass capacitor close to this pin. |
| 5 | +IN B | input | Non-inverting input of amplifier B. Rail-to-rail input, common-mode range -0.1 V to (V+)+0.1 V. Input bias current ~1 pA typical. |
| 6 | -IN B | input | Inverting input of amplifier B. Rail-to-rail input, common-mode range -0.1 V to (V+)+0.1 V. Input bias current ~1 pA typical. |
| 7 | OUT B | output | Output of amplifier B. Rail-to-rail output; typical short-circuit current ~55 mA. Output swings within ~8 mV (10 kohm load) / ~25 mV (2 kohm load) of the supply rails. |
| 8 | OUT C | output | Output of amplifier C. Rail-to-rail output; typical short-circuit current ~55 mA. Output swings within ~8 mV (10 kohm load) / ~25 mV (2 kohm load) of the supply rails. |
| 9 | -IN C | input | Inverting input of amplifier C. Rail-to-rail input, common-mode range -0.1 V to (V+)+0.1 V. Input bias current ~1 pA typical. |
| 10 | +IN C | input | Non-inverting input of amplifier C. Rail-to-rail input, common-mode range -0.1 V to (V+)+0.1 V. Input bias current ~1 pA typical. |
| 11 | V- | power_in | Negative supply / ground pin, shared by all four amplifiers. Tie to GND for single-supply operation or to the negative rail for split supplies. Bypass with a 0.1 uF capacitor close to the pin. |
| 12 | +IN D | input | Non-inverting input of amplifier D. Rail-to-rail input, common-mode range -0.1 V to (V+)+0.1 V. Input bias current ~1 pA typical. |
| 13 | -IN D | input | Inverting input of amplifier D. Rail-to-rail input, common-mode range -0.1 V to (V+)+0.1 V. Input bias current ~1 pA typical. |
| 14 | OUT D | output | Output of amplifier D. Rail-to-rail output; typical short-circuit current ~55 mA. Output swings within ~8 mV (10 kohm load) / ~25 mV (2 kohm load) of the supply rails. |
