AD9239BCPZ-250

The AD9239BCPZ-250 from Analog Devices is a high-performance quad, 12-bit analog-to-digital converter (ADC) designed for digitizing high-frequency signals. It offers a maximum sampling rate of 250 MSPS per channel and boasts a wide analog bandwidth of 780 MHz.

This ADC features a pipelined architecture and provides coded serial digital outputs with error correction code (ECC) per channel. Key electrical specifications include excellent linearity with typical DNL of ±0.3 LSB and INL of ±0.7 LSB. It achieves a Signal-to-Noise Ratio (SNR) of 65 dBFS and a Spurious-Free Dynamic Range (SFDR) of 77 dBc at 85 MHz input frequency and 250 MSPS sampling rate. The device operates from a single 1.8V supply.

Designed for demanding applications, the AD9239BCPZ-250 includes an on-chip temperature sensor and an internal reference that can be adjusted via SPI control. It supports various power-down modes and features a clock duty cycle stabilizer for consistent performance. The serial port interface is configurable, allowing for programmable headers and pin functions.

Packaged in a 72-lead LFCSP (72-VFQFN Exposed Pad, CSP), this surface-mount device is suitable for space-constrained designs. It operates within an industrial temperature range of -40°C to 85°C, making it a robust choice for communication receivers, broadband radios, radar systems, and test equipment.
