Analog Devices Inc. AD9219BCPZ-40

Overview

AD9219BCPZ-40 from Analog Devices is a quad-channel, 10-bit, 40 MSPS analog-to-digital converter with serial LVDS outputs, 1.8 V supply operation, and 315 MHz full-power analog bandwidth. It integrates four pipeline ADCs in one 48-lead LFCSP package and delivers 60 dB SNR and 78 dBc SFDR at Nyquist for ultrasound beamforming and quadrature radio receivers.

For engineers reviewing the AD9219BCPZ-40 datasheet, AD9219BCPZ-40 pinout, AD9219BCPZ-40 application, or AD9219BCPZ-40 equivalent, this page provides verified specifications, validated pin functions, confirmed industrial temperature range (−40°C to +85°C), RoHS-compliant packaging, and real-world use context for medical imaging and optical networking signal acquisition.

Technical Context

The AD9219BCPZ-40 implements four independent 10-bit pipeline ADC cores sharing a common 1.8 V AVDD supply and LVDS serial output interface compliant with ANSI-644. Each channel supports programmable clock/data alignment, offset binary coding, and individual power-down mode consuming <2 mW when disabled.

It features on-chip 1.0 V reference generation, 2 V p-p differential analog input range, and built-in deterministic/pseudorandom digital test pattern generation via SPI. The device multiplies the input sample clock internally to generate DDR-capable DCO (up to 390 MHz) and frame-synchronized FCO signals for reliable data capture.

FAQ

What is the maximum sampling rate supported by the AD9219BCPZ-40?

The AD9219BCPZ-40 is rated for a maximum sampling rate of 40 MSPS, as indicated by the "-40" suffix in its part number. This is a fixed-speed variant within the AD9219 family-distinct from the AD9219BCPZ-65, which supports up to 65 MSPS. Operation above 40 MSPS is not guaranteed and may violate AC specifications including SNR and SFDR.

Does the AD9219BCPZ-40 require an external reference voltage?

No, the AD9219BCPZ-40 includes an internal 1.0 V reference and operates fully with only AVDD and DRVDD supplies. External reference inputs (REFT/REFB/VREF/SENSE) are optional and used only when higher accuracy or custom reference scaling is needed. Default operation uses the internal reference with ±21 ppm/°C drift.

How many analog input channels does the AD9219BCPZ-40 support?

The AD9219BCPZ-40 integrates four independent analog-to-digital converter channels (A, B, C, D), each with dedicated differential inputs (VIN+ x / VIN− x), serial LVDS outputs (D+ x / D− x), and shared control interfaces. All four channels operate simultaneously with matched latency and gain/offset characteristics.

What package type is used for the AD9219BCPZ-40?

The AD9219BCPZ-40 is packaged in a 48-lead LFCSP (Lead Frame Chip Scale Package), designated CP-48-9 per the Rev. G datasheet. It measures 7 mm × 7 mm × 0.85 mm and features an exposed thermal pad that must be soldered to analog ground for proper thermal and electrical performance.

Can the AD9219BCPZ-40 output data in LSB-first format?

Yes, the AD9219BCPZ-40 supports configurable bit orientation via its SPI interface. By writing to the appropriate register, users can select either MSB-first (default) or LSB-first serial data output order-enabling seamless interoperability with FPGA logic that expects either convention without external bit-reversal logic.
