HTCSEMI · Operational Amplifier · SOP-14

HT20074ARZ from HTCSEMI, in a SOP-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 OUT 1 output Output of channel 1, a class AB rail-to-rail output stage (page 16); output current is limited to ±100 mA maximum (page 3).
2 IN− 1 input Inverting input of channel 1; input current must be limited to ±10 mA, and 500 Ω series resistors are recommended when differential input exceeds 26 V (pages 3 and 16).
3 IN+ 1 input Non-inverting input of channel 1; common-mode voltage must stay between VSS and VDD − 1.35 V (page 3).
4 VDD power_in Positive supply; single-supply operating range is 2.7 V to 36 V (split supply ±1.35 V to ±18 V) with absolute maximum supply of 40 V (page 3).
5 IN+ 2 input Non-inverting input of channel 2; common-mode voltage must stay between VSS and VDD − 1.35 V (page 3).
6 IN− 2 input Inverting input of channel 2; input current must be limited to ±10 mA (pages 3 and 16).
7 OUT 2 output Output of channel 2, a class AB rail-to-rail output stage with output current limited to ±100 mA maximum (pages 3 and 16).
8 OUT 3 output Output of channel 3, a class AB rail-to-rail output stage with output current limited to ±100 mA maximum (pages 3 and 16).
9 IN− 3 input Inverting input of channel 3; input current must be limited to ±10 mA (pages 3 and 16).
10 IN+ 3 input Non-inverting input of channel 3; common-mode voltage must stay between VSS and VDD − 1.35 V (page 3).
11 VSS power_in Negative supply (ground in single-supply use); the input common-mode range is referenced to VSS (pages 3 and 16).
12 IN+ 4 input Non-inverting input of channel 4; common-mode voltage must stay between VSS and VDD − 1.35 V (page 3).
13 IN− 4 input Inverting input of channel 4; input current must be limited to ±10 mA (pages 3 and 16).
14 OUT 4 output Output of channel 4, a class AB rail-to-rail output stage with output current limited to ±100 mA maximum (pages 3 and 16).
