The Analog Devices MAX9910EXK+T is a single-channel general-purpose operational amplifier in a SC-70-5 package. It delivers a 200 kHz gain-bandwidth product with a 0.1 V/µs slew rate, rail-to-rail output swing, and draws only 4 µA supply current. The 1.8 V to 5.5 V supply span and 1 pA input bias current make it a natural fit for battery-powered sensor interfaces, portable instrumentation, and low-frequency signal conditioning where every microamp counts.
200 kHz GBW at 4 µA — what that means for the BOM
The 200 kHz gain-bandwidth product paired with a 4 µA supply current is the headline trade-off. This part is not for high-speed ADC drivers or video buffers; it is sized for DC-accurate amplification, active filtering below a few kilohertz, and low-side current sensing where the bandwidth requirement is modest. The 0.1 V/µs slew rate confirms the same — expect clean signal reproduction for audio-band or slower sensor outputs, not fast pulse edges. The rail-to-rail output keeps dynamic range in a 1.8 V single-supply system without a second rail.
Package and pinout — SC-70-5
The MAX9910EXK+T comes in a 5-lead SC-70 package (also known as SOT-353). It is a surface-mount part, supplied on Tape & Reel or Cut Tape. The pinout follows the standard single op-amp layout: non-inverting input, inverting input, output, V+, and V-. Board footprint matches the SC-70-5 land pattern; no surprises if you are replacing a similar part in the same package. Store the reels dry — the moisture sensitivity level is not stated here, but SC-70 reels should be treated as MSL 1 unless the reel label says otherwise.
Lifecycle and sourcing
The MAX9910EXK+T is listed as Active and ROHS3 compliant. No end-of-life notice or last-time-buy window has been announced. For a BOM line that needs a low-power, single-supply op-amp in a tiny footprint, this part is a safe long-term choice — no urgency to stockpile or qualify a replacement. Sourced and quoted to order through independent distribution.
