**Texas Instruments** · Current Sense Amplifiers · VSSOP-8

INA200AQDGKRQ1 from Texas Instruments, in a VSSOP-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 | Vs | power_in | Analog power supply input rated 2.7V to 18V. |
| 2 | OUT | output | Analog output voltage proportional to differential input VSENSE amplified by gain of 20V/V (INA200-Q1), output range limited by supply voltage VS. |
| 3 | CMPIN | input | Comparator positive input for over-current threshold setting, accepts input voltage range 0V to (VS - 1.5V). |
| 4 | GND | power_in | Analog ground reference. |
| 5 | RESET | input | Active-low comparator reset input with internal 2MΩ pull-down; open or low places comparator in transparent mode; RESET threshold 1.1V. |
| 6 | CMPOUT | output | Open-drain comparator output pullable to external voltage range 2.7V to 18V; low-level output voltage 220mV to 300mV at IOL = 2.35mA. |
| 7 | VIN- | power_in | Negative differential input connected to low-side of shunt resistor; differential voltage range ±18V, common-mode range -16V to +80V. |
| 8 | VIN+ | power_in | Positive differential input connected to high-side of shunt resistor; differential voltage range ±18V, common-mode range -16V to +80V. |
