The AD7981HFZ from Analog Devices is a high-performance, 16-bit successive approximation analog-to-digital converter (ADC) specifically designed for extreme high-temperature operation. It supports a pseudo-differential analog input range and achieves a maximum sampling rate of 600 kSPS with zero latency.
Key electrical specifications include a resolution of 16 bits with no missing codes, INL of ±2.5 LSB maximum, and DNL of ±0.9 LSB maximum. The device offers a dynamic range of 92 dB and an SNR of 91 dB at 1 kHz with a 5V reference. Power consumption is notably low, with a typical value of 2.25 mW at 600 kSPS (VDD only).
This ADC features a versatile serial interface compatible with SPI, QSPI, MICROWIRE, and DSP protocols, allowing for daisy-chaining multiple ADCs. It operates from a single 2.5V supply with a 1.8V to 5V logic interface. The AD7981HFZ is available in a compact 10-lead, 3 mm × 3 mm MSOP package, suitable for surface mounting.
Applications for the AD7981HFZ include oil and gas exploration, avionics, heavy industrial systems, and other high-temperature environments requiring precise data acquisition.
The supply voltage range is 2.375V to 2.625V.
The AD7981HFZ is available in a 10-lead CFlatPack surface-mount package.
The specified temperature range is -55°C to +175°C (per datasheet).
The AD7981HFZ is listed as RoHS3 Compliant, but this is unverified.
