AD8611ARZ-REEL7

Analog Devices · Comparators · SOIC-8

AD8611ARZ-REEL7 from Analog Devices, in a SOIC-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 V+ power_in Positive supply terminal; the datasheet specifies single-supply operation from 3 V to 5 V and a 7.0 V maximum total analog supply.
2 IN+ input Noninverting analog input of the differential input stage; input common-mode range is −200 mV to 2.0 V below V+ (typically 0.0 V to 3.0 V at 5 V supply) and the input must stay within that range for proper operation.
3 IN- input Inverting analog input of the differential input stage; the same common-mode voltage range and ±5 V maximum differential input voltage apply as for IN+.
4 V- power_in Negative supply terminal; the datasheet specifies test conditions with V− = 0 V (ground) for single-supply operation.
5 LATCH input Latch enable input, TTL/CMOS compatible with logic high at least 2.0 V and logic low at most 0.8 V; the latch is not functional when VCC is below 4.3 V and should be tied low for low VCC operation.
6 GND power_in Negative logic supply (ground reference for the digital/latch section), the datasheet's only ground pin on the SOIC package.
7 QA output One of two complementary outputs for channel A; the output swings from ground to about 1 V below V+ with no load and is rated up to 10 mA output current without added propagation delay.
8 QA output One of two complementary outputs for channel A; the output swings from ground to about 1 V below V+ with no load and is rated up to 10 mA output current without added propagation delay.
