The document describes the features and characteristics of the AD7952, a 14-bit, 1 MSPS, differential, programmable input PulSAR® ADC. The ADC offers multiple programmable input ranges through pins or a serial SPI®-compatible interface. It has a throughput of 1 MSPS (warp mode) and a resolution of 14 bits with no missing codes. It features low INL, high SNR, and utilizes the iCMOS® process technology. The ADC includes a 5V internal reference with low drift, a temperature output, and has no pipeline delay due to its SAR architecture. It supports both parallel and serial interfaces and has low power dissipation. The AD7952 is suitable for applications such as process controls, medical instruments, and high-speed data acquisition.
The AD7952 ADC from Analog Devices provides 14‑bit resolution with no missing codes and supports up to 1 MSPS throughput in warp mode. It offers multiple programmable input ranges (±5 V, ±10 V, +5 V, +10 V) and can be configured via hardware pins or a serial configuration port.
The device includes both parallel and serial (SPI/QSPI/MICROWIRE/DSP) interfaces, an internal 5 V reference, and operates from –40 °C to +85 °C. Detailed specifications, pin descriptions, timing diagrams, and application guidelines are provided throughout the handbook.
