The AD7938BSUZ is a 12-bit, high-speed, low-power successive approximation (SAR) analog-to-digital converter (ADC) from Analog Devices. It operates from a single 2.7V to 5.25V power supply and features a throughput rate of 1.5 MSPS. The device includes a low-noise, wide-bandwidth differential track-and-hold amplifier and an on-chip 2.5V reference with ±0.2% maximum accuracy at 25°C.
The ADC provides 8 analog input channels with a software-configurable sequencer. Inputs can be configured as 8 single-ended, 4 fully differential, 4 pseudo-differential, or 7 pseudo-differential channels. The device uses a SAR architecture with a MUX-S/H-ADC configuration and a 1:1 S/H to ADC ratio, ensuring no pipeline delays.
Power consumption is 6 mW maximum at 1.5 MSPS with 3V supplies and 13.5 mW maximum with 5V supplies. The device achieves 69 dB SINAD at a 50 kHz input frequency. A full shutdown mode reduces current to 2 µA maximum. The high-speed parallel interface supports word and byte modes.
The AD7938BSUZ is available in a 32-lead TQFP package (7x7 mm) for surface mount assembly. It operates over a temperature range of -40°C to +85°C, making it suitable for industrial applications.
The AD7938BSUZ is a 12-bit analog-to-digital converter.
The datasheet specifies a typical throughput rate of 1.5 MSPS. The database lists 625 kSPS, which may be a derated or alternate condition.
