LTC6752HUD-3#PBF

Analog Devices · Comparators · QFN-12-EP(3x3)

LTC6752HUD-3#PBF from Analog Devices, in a QFN-12-EP(3x3). 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 VDD power_in Positive supply for the output stage, typically 1.71V to 3.5V above VEE.
2 VCC power_in Positive supply for the input stage, 2.45V to 5.25V above VEE.
3 VEE power_in Negative power supply, normally tied to ground.
4 +IN input Positive comparator input; voltage range can go from VEE to VCC.
5 NC unconnected No internal connection.
6 -IN input Negative comparator input; voltage range can go from VEE to VCC.
7 ~{SHDN} input Active-low shutdown with threshold 0.6V above VEE; the comparator is enabled when the pin is left unconnected.
8 ~{LE}/HYST input Latches the output when taken within 300mV above VEE and adjusts hysteresis (typically 5mV when left unconnected, disabled above 1.7V).
9 VEE power_in Negative power supply, normally tied to ground.
10 ~{Q} output Complementary comparator output (LTC6752-3 only), the logical inversion of Q.
11 NC unconnected No internal connection.
12 Q output Comparator output, driven high when +IN > -IN and low when +IN < -IN.
13 VEE power_in Exposed pad, VEE; must be soldered to the PCB.
