MAX1162ACUB+T Overview
A SAR ADC is a type of data converter that performs a binary search through an internal capacitive DAC to digitize an analog signal in N conversion cycles for N bits of resolution. As part of the broader data-acquisition signal chain (sensor -> front-end amplifier -> anti-alias filter -> ADC -> digital host), SAR ADCs are prized for deterministic latency, low latency-to-sample ratios, and excellent DC accuracy without the pipeline delay of pipelined architectures.
Key specifications include 16-bit no-missing-codes performance, an input-voltage range of 0 to VREF, an internal 4 MHz track-and-hold, an SPI/QSPI/MICROWIRE-compatible serial output. The MAX1162ACUB+T integrates the reference buffer internally, so only an external reference voltage (typically +5V for full-scale) is required. The automatic shutdown between conversions reduces average supply current dramatically at lower throughput rates, making the part ideal for battery-powered and duty-cycled applications.
Architecture-wise, the device uses a charge-redistribution capacitive DAC array combined with a precision comparator and successive-ration logic, with an internal input track-and-hold that accepts fast-slewing signals up to the conversion rate without external buffering. The serial interface is straightforward: CS, DOUT, and SCLK form a standard 3-wire SPI port compatible with most microcontrollers and DSPs.
Typical applications include portable data loggers, hand-held measurement instruments, battery-powered sensors and instrumentation, industrial process control analog front-ends, and medical monitoring devices. Its small 10-pin uMAX footprint suits space-constrained PCB designs where density matters.
When designing with this ADC, allocate adequate settling time for the external reference and add a 0.1 µF bypass capacitor close to VDD. The SSTRB (or DSP-style) output can be polled to confirm conversion completion before clocking out results.

Design Notes
Place a 0.1 uF ceramic bypass capacitor as close as possible to the VDD pin (Pin 4), with a 10 uF bulk tantalum or ceramic on the VDD trace. According to the Maxim datasheet, the MAX1162ACUB+T draws typical active supply current during conversion and drops to 10 uA in shutdown. Adequate VDD decoupling is critical to achieving the datasheet's 16-bit no-missing-codes performance.
Keep analog (AIN, REF) traces short and away from digital switching lines (SCLK, DOUT, CS) to minimize digital crosstalk into the analog input. Use a ground plane and place the reference capacitor (typically 0.1 uF to 10 uF) close to the REF pin. Per Maxim recommendations, star-ground the AGND and DGND connections at a single point near the IC.
Drive the SCLK input with a clean digital signal; excessive ringing or slow edges can cause double-clocking and corrupt the conversion result. Per the Maxim datasheet, SCLK frequencies up to 4 MHz are supported. Add a small series resistor (22-33 ohm) at the SCLK source if long traces cause reflections, and ensure CS transitions low at least 10 ns before the first SCLK rising edge.
Do not leave the REF pin floating - always connect a low-noise external reference (e.g., MAX6125 or equivalent) or filtered VDD-derived voltage. Per the Maxim datasheet, the input-voltage range is 0 to VREF, so an unstable or noisy REF directly degrades conversion accuracy. Also ensure CS returns high between conversions to trigger automatic power-down and minimize average supply current.
