12-bit SAR ADC with flexible input mux
The MAX1246AEEE+ is a 12-bit successive-approximation-register (SAR) ADC from Analog Devices, sampling at 133k samples per second. Its architecture — a multiplexer feeding a sample-and-hold driving a single converter — lets one IC handle either two differential or four single-ended inputs, selected through the SPI interface.
Single-supply rail and industrial temperature grade
The external or internal reference option (Reference Type: External, Internal) means you can use the on-chip bandgap for a standalone design or inject a precision external reference when the system demands tighter drift over temperature.
Board-fit: 16-pin QSOP footprint
The MAX1246AEEE+ ships in a 16-pin SSOP package (0.154-inch body width, 3.90 mm) with an equivalent 16-QSOP supplier package designation. Surface-mount assembly on a standard 0.025-inch pitch footprint; the tube delivery suits pick-and-place lines that prefer tube-fed rather than tape-and-reel input.
Lifecycle and compliance status
Analog Devices lists the MAX1246AEEE+ as Active (current production) with RoHS3 compliance.
