INA204AIDR

Texas Instruments · Current Sense Amplifiers · SOIC-14

INA204AIDR from Texas Instruments, in a SOIC-14. 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 Power supply input; the recommended operating supply is 2.7 V to 18 V (12 V nominal) and the absolute maximum is 18 V.
2 OUT output Current-shunt monitor analog output voltage, limited to GND - 0.3 V to (VS) + 0.3 V per the absolute maximum ratings.
3 CMP1 IN-/0.6-V Ref input Comparator 1 negative input that can be used to override the internal 0.6-V reference; comparator analog input limits are GND - 0.3 V to (VS) + 0.3 V.
4 CMP1 IN+ input Comparator 1 positive input; comparator analog input limits are GND - 0.3 V to (VS) + 0.3 V.
5 CMP2 IN+ input Comparator 2 positive input; comparator analog input limits are GND - 0.3 V to (VS) + 0.3 V.
6 CMP2 IN-/0.6V REF input Comparator 2 negative input that can be used to override the internal 0.6-V reference; comparator analog input limits are GND - 0.3 V to (VS) + 0.3 V.
7 GND power_in Ground reference for the device.
8 CMP1 RESET input Active-low output reset input for comparator 1 (latched comparator); reset pin limits are GND - 0.3 V to (VS) + 0.3 V.
9 CMP2 DELAY input Connect an optional capacitor to this pin to adjust the comparator 2 delay; the VREF and CMP2 delay pin rating is GND - 0.3 V to 10 V.
10 CMP2 OUT output Comparator 2 open-drain output; the comparator output pin rating is GND - 0.3 V to 18 V.
11 CMP1 OUT output Comparator 1 open-drain output; the comparator output pin rating is GND - 0.3 V to 18 V.
12 1.2-V REF OUT output 1.2-V internal reference output; the VREF pin rating is GND - 0.3 V to 10 V.
13 VIN- power_in Connect to the low side of the shunt; the common-mode input range is -16 V to 80 V and the differential input range is -18 V to 18 V.
14 VIN+ power_in Connect to the high side of the shunt; the common-mode input range is -16 V to 80 V and the differential input range is -18 V to 18 V.
