# ADCMP553BRMZ

**Analog Devices** · Comparators · MSOP-8

ADCMP553BRMZ from Analog Devices, in a MSOP-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 | ~{LEA} | input | Complementary latch enable input for channel A: in compare mode (logic low) the output tracks the input, in latch mode (logic high) the output holds the prior input state, and it must be driven together with LEA. |
| 2 | LEA | input | Latch enable input for channel A: in compare mode (logic high) the output tracks the input, in latch mode (logic low) the output holds the prior input state, and it must be driven together with ~{LEA}. |
| 3 | +INA | input | Noninverting analog input of the differential input stage for channel A, which must be driven in conjunction with the inverting input. |
| 4 | -INA | input | Inverting analog input of the differential input stage for channel A, which must be driven in conjunction with the noninverting input. |
| 5 | ~{QA} | output | Complementary PECL output for channel A that is logic low when the noninverting input is greater than the inverting input in compare mode. |
| 6 | QA | output | PECL output for channel A that is logic high when the noninverting input is greater than the inverting input in compare mode. |
| 7 | VCC | power_in | Positive supply terminal, specified for 3.135 V to 5.25 V. |
| 8 | AGND | power_in | Analog ground. |
