# ICL7611DCPAZ

**RENESAS** · Pre-ordered Chips · PDIP-8

ICL7611DCPAZ from RENESAS, in a PDIP-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 | BAL | passive | Offset null terminal; a 25k pot between the BAL terminals with the wiper connected to V+ provides input offset nulling. |
| 2 | -IN | input | Inverting input, internally protected by input diodes; no voltage greater than 0.3V beyond the supply rails may be applied to any pin to avoid latchup. |
| 3 | +IN | input | Non-inverting input; on the ICL7611 the common-mode range is limited to the supply rails, while the ICL7612 extends the input CMVR 0.1V beyond each rail for VSUPPLY of 1.5V or more. |
| 4 | V- | power_in | Negative supply rail; the device operates from supply voltages of 1V to 8V, with V+ to V- absolute maximum of 18V. |
| 5 | BAL | passive | Second offset null terminal, used together with pin 1 and a 25k pot with wiper to V+ for input offset nulling. |
| 6 | OUT | output | Amplifier output, fully protected against short circuits to ground or to either supply; the output swings to within a few millivolts of the supply rails. |
| 7 | V+ | power_in | Positive supply rail; the device operates from supply voltages of 1V to 8V, with V+ to V- absolute maximum of 18V. |
| 8 | IQ SET | input | Quiescent current programming pin: tie to V+ for IQ = 10µA, to ground for IQ = 100µA, or to V- for IQ = 1mA; if ground is not possible, any voltage from V+ - 0.8 to V- + 0.8 can be used for 100µA. |
