Analog Devices Inc. AD9216BCPZ-105

Overview

AD9216BCPZ-105 from Analog Devices is a dual, 10-bit, 105 MSPS analog-to-digital converter (ADC) with differential input, integrated voltage reference, and clock duty cycle stabilizer. It delivers SNR = 57.6 dBc and SFDR = 74 dBc at Nyquist, operates from a single 3 V supply, and consumes 300 mW total power. It is used in ultrasound equipment and IF sampling for communications receivers.

For engineers reviewing the AD9216BCPZ-105 datasheet, AD9216BCPZ-105 pinout, AD9216BCPZ-105 application, or AD9216BCPZ-105 equivalent, key selection considerations include guaranteed no missing codes over −40°C to +85°C, 300 MHz analog input bandwidth, crosstalk < −80 dB, pipeline latency of 6 cycles, and support for offset binary or twos complement output formats.

Technical Context

The AD9216BCPZ-105 employs a multistage differential pipelined architecture with output error correction logic to ensure 10-bit accuracy and no missing codes across temperature. Its dual sample-and-hold amplifiers support both differential and single-ended inputs up to 200 MHz.

Dual independent clock inputs (CLK_A, CLK_B) control conversion timing, and the integrated duty cycle stabilizer maintains performance across wide clock duty cycle variations. Digital outputs are CMOS-compatible, driven by DRVDD = 2.5 V, with 10-bit parallel data per channel and programmable output enable (OEB_A/OEB_B).

FAQ

What is the guaranteed operating temperature range for the AD9216BCPZ-105?

The AD9216BCPZ-105 is specified over the industrial temperature range of −40°C to +85°C. All DC and AC specifications-including SNR, SFDR, INL, DNL, and no missing codes-are guaranteed across this full range when operated within recommended supply voltages (AVDD = 2.7 V to 3.3 V, DRVDD = 2.25 V to 3.3 V). Thermal derating is not required within these limits.

Does the AD9216BCPZ-105 require external reference components?

No, the AD9216BCPZ-105 integrates a precision 1.0 V voltage reference and supports both internal reference operation and external reference input via VREF, REFT_A/REFB_A, and REFT_B/REFB_B pins. When using the internal reference, no external components are needed; for improved stability or custom scaling, an external reference can be applied directly to the VREF pin.

How does the clock duty cycle stabilizer (DCS) function in the AD9216BCPZ-105?

The DCS circuit in the AD9216BCPZ-105 actively corrects duty cycle distortion on CLK_A and CLK_B inputs, enabling full AC performance (SNR ≥ 57.6 dBc, SFDR ≥ 74 dBc) even with clock duty cycles ranging from 40% to 60%. It operates automatically when DCS pin is high and requires no external components-eliminating need for clock buffer ICs or RC networks in system clock trees.

Can both channels of the AD9216BCPZ-105 be powered down independently?

Yes, the AD9216BCPZ-105 provides independent channel power-down control via PDWN_A and PDWN_B pins. Driving either pin high powers down its respective analog section, reducing that channel's power consumption to ~3 mW while preserving digital interface functionality. Both channels may be active, one active/one down, or both down-enabling dynamic power scaling in battery-operated or thermally constrained systems.

What digital output interface options does the AD9216BCPZ-105 support?

The AD9216BCPZ-105 supports parallel CMOS digital outputs with 10-bit data per channel (D0_A–D9_A and D0_B–D9_B), configurable for offset binary or twos complement format via the DFS pin. Outputs are driven by DRVDD (2.5 V typical), feature 1 ns rise/fall times, and include per-channel output enable (OEB_A/OEB_B) for high-impedance bus sharing-compatible with Xilinx Artix-7, Intel Cyclone V, and similar FPGA I/O standards.
