Zero-drift topology — what the 0.8 µV offset means for the BOM
The 0.8 µV input offset is the headline spec: it is the result of a chopper-stabilized zero-drift architecture. For a precision weigh-scale or thermocouple amplifier, this eliminates the need for an external offset-trim pot or a calibration step at final test. The 10 pA input bias current further reduces error in high-impedance sensor circuits. The rail-to-rail output lets the part swing close to the supply rails, preserving dynamic range in a single-supply system.
150 mA output drive — not just a signal amp
The 150 mA output current per channel is unusually high for a zero-drift op-amp. This means the MAX9617AXT+T can directly drive a moderate load — a reference input, a small relay coil with a flyback diode, or a heavy analog-to-digital converter reference buffer — without a separate buffer stage. The 0.7 V/µs slew rate keeps the output responsive for signals up to a few tens of kilohertz, consistent with the 1.5 MHz gain-bandwidth product.
Package and mounting
The part comes in a SC-70-6 package (supplier device package SC-70-6, also listed as SC-88 / SOT-363). It is a surface-mount package. The Tape & Reel and Cut Tape options cover both prototyping and production reels. The RoHS3 compliance is current; no exemption expiry to track.
No last-time-buy or end-of-life notices are recorded. The part is available through independent distribution and is quoted to order against an RFQ.
