LTC1540IMS8#PBF 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 | GND | power_in | Ground pin, to be connected to V- for single-supply operation. |
| 2 | V- | power_in | Negative supply, which should be more negative than GND and connected to ground for single-supply operation. |
| 3 | IN+ | input | Noninverting comparator input with common-mode range from V- to V+ - 1.3V and typical input current of 10pA at 25°C. |
| 4 | IN- | input | Inverting comparator input with common-mode range from V- to V+ - 1.3V and typical input current of 10pA at 25°C. |
| 5 | HYST | input | Hysteresis input, connected to REF if not used, with input voltage range from VREF to VREF - 50mV. |
| 6 | REF | output | Reference output of 1.182V with respect to V-, able to source up to 1mA and sink 10µA at 25°C, and to drive a 0.01µF bypass capacitor without oscillation. |
| 7 | V+ | power_in | Positive supply with operating voltage from 2V to 11V. |
| 8 | OUT | output | Comparator CMOS output swinging from GND to V+, able to source up to 40mA and sink 5mA. |
