The AD9215 is a 10-bit, 65/80/105 MSPS, 3 V A/D converter from Analog Devices. It features single 3 V supply operation, SNR = 58 dBc (to Nyquist), SFDR = 77 dBc (to Nyquist), low power ADC core, differential input, 300 MHz bandwidth, On-chip reference and sample-and-hold amplifier, DNL = ±0.25 LSB, flexible analog input, offset binary or twos complement data format, clock duty cycle stabilizer, and is used in ultrasound equipment, IF sampling in communications receivers, battery-powered instruments, hand-held scopemeters, and low cost digital oscilloscopes.
The document describes the AD9215 as a monolithic, single 3 V supply ADC featuring a high-performance sample-and-hold amplifier and voltage reference. It utilizes a multistage differential pipelined architecture with output error correction logic to ensure no missing codes over its full operating temperature range.
Key features include operation from a single 2.7 V to 3.3 V supply, a wide bandwidth of 300 MHz for differential inputs, and flexible analog input ranges selectable between 1 V p-p and 2 V p-p. The device is available in two packages: a 28-lead surface-mount plastic package and a 32-lead chip scale package.
