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. |
