AD7664ACP

Analog To Digital Converters (ADC) Overview

The AD7664ACP is a 16-bit, 570 kSPS PulSAR analog-to-digital converter operating from a single 5 V supply. It features a throughput of 570 kSPS in Warp Mode, 500 kSPS in Normal Mode, and 444 kSPS in Impulse Mode. The device offers a maximum integral nonlinearity of ±2.5 LSBs with no missing codes and a typical signal-to-noise ratio of 90 dB at 45 kHz. Power dissipation reaches 115 mW maximum, dropping to 21 µW at 100 SPS in Impulse Mode and 7 µW in power-down.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to confirm package type and temperature range. Ensure compatibility with host system voltage requirements for AVDD, DVDD, and OVDD supplies. Confirm that the selected variant meets the required thermal management specifications for the intended application environment.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and high sampling rate are required without pipeline delay. Choose Warp Mode for continuous high-speed applications requiring strict timing between conversions. Opt for Impulse Mode in battery-operated designs where power consumption must scale with throughput. Ensure the analog input range matches the 0 V to VREF specification.

Analog To Digital Converters (ADC) Part Context

The AD7664 belongs to Analog Devices' PulSAR family of CMOS ADCs. It serves as a pin-to-pin compatible upgrade to the AD7660, offering improved performance within a 48-lead LQFP or LFCSP package. The device utilizes a 0.6 micron CMOS process to deliver high accuracy and low power consumption across the industrial temperature range.

Analog To Digital Converters (ADC) Replacement Considerations

The AD7664 is explicitly documented as a pin-to-pin compatible upgrade for the AD7660. Designers replacing legacy AD7660 units can utilize the AD7664 without modifying the PCB footprint or basic interface connections.
