Quad general-purpose op-amp for industrial signal chains
The Renesas HA17902AFP-E is a quad general-purpose operational amplifier in a 14-PSOP surface-mount package. It integrates four independent op-amp circuits, each drawing 800 µA supply current, making it suitable for multi-channel signal conditioning in industrial control, sensor interface, and low-speed data acquisition where board space and per-channel power budget matter. The 0.19 V/µs slew rate limits the large-signal bandwidth to roughly 12 kHz at 5 V output swing, so this part fits DC and low-frequency AC paths — thermocouple amplifiers, strain gauge bridges, or set-point comparators — not audio or fast ADC drivers.
The 0.19 V/µs slew rate is the headline limiter: a 5 V step settles in about 26 µs, so the part cannot track signals above a few kilohertz without distortion. The 2 mV typical input offset is moderate for a general-purpose amplifier — acceptable for 8-bit or 10-bit accuracy loops, but if your application requires sub-millivolt precision across temperature, you will need an auto-zero or chopper-stabilized part. The 30 nA input bias current is low enough for most resistive sensor dividers without adding significant voltage error.
Package and footprint — 14-PSOP versus standard SOIC
The HA17902AFP-E uses a 14-PSOP package (Renesas' designation for a 14-lead small-outline package with 5.50 mm body width). The supplier device package is 14-PSOP. Verify the pad geometry against the mechanical drawing before committing the layout.
