24-bit sigma-delta ADC with 62.5 kSPS throughput
The AD4116BCPZ-RL7 is a 24-bit sigma-delta ADC from Analog Devices that samples at 62.5 kSPS — fast enough for multi-channel industrial data acquisition where you need to digitize several sensor signals in a round-robin scan without aliasing. It accepts both differential and single-ended inputs through an internal MUX-ADC front end, so a single part handles thermocouple pairs (differential) and 0-10 V process signals (single-ended) on the same BOM line.
Supply rails and digital interface flexibility
The analog supply runs from 4.5 V to 5.5 V, while the digital supply accepts 2 V to 5.5 V — this split-rail design lets the ADC talk directly to a 3.3 V or 5 V host controller without an external level translator, saving board space and BOM cost. Data interface options include DSP, Microwire, QSPI, and standard SPI — the serial bus is compatible with most MCU SPI peripherals; the Microwire mode is handy for legacy 8051 or PIC designs that lack a full SPI engine.
Package, temperature range, and lifecycle
Housed in a 40-lead LFCSP-VQ (6x6 mm) with an exposed pad — the pad must be soldered to a thermal land on the PCB to keep the junction temperature within the -40°C to 105°C operating range; a reflow profile with a peak around 260°C is typical for this package.
