Micropower dual op-amp for continuous sensor conditioning
The Microchip MCP617-I/SN is a dual CMOS operational amplifier designed for low-power, single-supply applications where every microamp of quiescent current is budgeted. Each of its two channels draws 19 µA typical supply current while delivering a 190 kHz gain-bandwidth product and rail-to-rail output swing. The 0.08 V/µs slew rate tells you this is a micropower part — the large-signal bandwidth is intentionally limited to keep the bias current low.
Where the 190 kHz GBW and 19 µA supply land on the BOM
The 190 kHz gain-bandwidth product sets the usable closed-loop bandwidth. For a gain-of-10 stage, the -3 dB point sits around 19 kHz — enough for audio-band anti-aliasing or sensor filtering, but not for high-speed data acquisition or switching amplifier loops. The 19 µA per-channel supply current (38 µA total for both amplifiers) is the headline spec for battery life: in a 3.3 V system, the two amplifiers together consume about 125 µW quiescent. That makes the MCP617-I/SN a fit for always-on sensor interfaces in IoT nodes, portable medical monitors, or field transmitters where the op-amp stays powered while the microcontroller sleeps.
Microchip lists the MCP617-I/SN as Active.
Sourcing and RFQ posture
Because the part is Active and widely stocked, lead times are typically short — but the exact position depends on the quantity and the supplier's inventory at the moment of inquiry. Submit an RFQ for a firm price and delivery commitment.
