HT4582ARZ

HTCSEMI · Operational Amplifier · SOP-8

HT4582ARZ from HTCSEMI, in a SOP-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 OUT1 output Output of amplifier channel 1; the datasheet gives a maximum output voltage of ±12 V minimum at RL = 600 Ω (VCC = ±15 V).
2 -IN1 input Inverting input of amplifier channel 1; common-mode input voltage range is ±12 V minimum (±13 V typical) at RL ≥ 10 kΩ.
3 +IN1 input Non-inverting input of amplifier channel 1; common-mode input voltage range is ±12 V minimum (±13 V typical) at RL ≥ 10 kΩ.
4 VEE power_in Negative power supply; the datasheet test conditions use VEE = -15 V and the absolute maximum supply voltage is 21 V (VCC to VEE).
5 +IN2 input Non-inverting input of amplifier channel 2; common-mode input voltage range is ±12 V minimum (±13 V typical) at RL ≥ 10 kΩ.
6 -IN2 input Inverting input of amplifier channel 2; common-mode input voltage range is ±12 V minimum (±13 V typical) at RL ≥ 10 kΩ.
7 OUT2 output Output of amplifier channel 2; the datasheet gives a maximum output voltage of ±12 V minimum at RL = 600 Ω (VCC = ±15 V).
8 VCC power_in Positive power supply; the absolute maximum power supply voltage is 21 V and the datasheet test conditions use VCC = +15 V.
