The AD9245BCPZ-20 is a 14-bit, 20 MSPS analog-to-digital converter (ADC) from Analog Devices, part of the AD9245 family. It uses a multistage differential pipelined architecture with output error correction logic to provide 14-bit accuracy and guarantee no missing codes over the full operating temperature range. Key electrical specifications include a signal-to-noise ratio (SNR) of 72.7 dBc to Nyquist, spurious-free dynamic range (SFDR) of 83.0 dBc to Nyquist, and differential nonlinearity (DNL) of ±0.5 LSB typical. Power dissipation is only 90 mW at 20 MSPS, making it suitable for power-sensitive applications.
The ADC supports both differential and single-ended inputs with a flexible analog input voltage range of 1 V p-p to 2 V p-p. It includes an on-chip reference and sample-and-hold amplifier. The data interface is parallel, supporting offset binary or twos complement output formats. The device operates from a single 3 V analog supply (2.7 V to 3.6 V) and a digital supply of 2.25 V to 3.6 V. It is specified for the industrial temperature range of -40°C to 85°C.
The AD9245BCPZ-20 is housed in a 32-LFCSP-WQ (5x5) surface mount package (32-WFQFN exposed pad CSP). Typical applications include medical imaging equipment, IF sampling in communications receivers (WCDMA, CDMA-One, CDMA-2000, TDS-CDMA), battery-powered instruments, hand-held scopemeters, spectrum analyzers, and power-sensitive military systems.
The analog supply voltage range is 2.7 V to 3.6 V, and the digital supply voltage range is 2.25 V to 3.6 V.
It is available in a 32-LFCSP-WQ (5x5) surface mount package, which is a 32-WFQFN exposed pad CSP.
The operating temperature range is -40°C to 85°C.
The part is listed as RoHS3 compliant, but this information is unverified.
