Analog Devices Inc. AD9216BCPZ-80

Overview

AD9216BCPZ-80 from Analog Devices is a dual-channel, 10-bit, 80 MSPS analog-to-digital converter (ADC) fabricated in advanced CMOS. It features integrated sample-and-hold amplifiers, differential analog inputs with 300 MHz bandwidth, on-chip voltage reference, and clock duty cycle stabilizer. It operates from a single 3 V supply and delivers 57.6 dBc SNR at Nyquist for IF sampling in communications receivers.

For engineers reviewing the AD9216BCPZ-80 datasheet, AD9216BCPZ-80 pinout, AD9216BCPZ-80 application, or AD9216BCPZ-80 equivalent, key selection considerations include its guaranteed no-missing-codes performance over −40°C to +85°C, channel crosstalk < −80 dB, dual independent power-down control, and support for offset binary or twos complement output formats.

Technical Context

The AD9216BCPZ-80 employs a multistage differential pipelined architecture with output error correction logic to ensure 10-bit accuracy and monotonicity across temperature. Its dual SHA inputs support both differential and single-ended configurations, with user-selectable input ranges via internal 1.0 V reference or external reference mode.

Each channel has independent clock inputs (CLK_A/CLK_B), output enable (OEB_A/OEB_B), and power-down (PWDN_A/PWDN_B) controls. The duty cycle stabilizer (DCS) compensates for clock duty cycle variation, preserving AC performance without requiring precise 50% clock edges.

FAQ

What is the maximum analog input frequency supported by the AD9216BCPZ-80?

The AD9216BCPZ-80 specifies 300 MHz analog bandwidth - meaning it maintains ≤3 dB signal attenuation up to 300 MHz. However, for Nyquist-compliant sampling, the maximum fundamental input frequency is 40 MHz (half of 80 MSPS). Higher input frequencies may be captured using undersampling techniques, provided aliasing is managed via filtering.

Does the AD9216BCPZ-80 require external reference components?

No. The AD9216BCPZ-80 integrates a precision 1.0 V voltage reference with ±2 mV output error and ±15 ppm/°C drift. External reference is optional and only needed when higher accuracy or custom full-scale range is required; the internal reference supports both shared and independent reference modes via the SHARED_REF pin.

How does the clock duty cycle stabilizer (DCS) function in the AD9216BCPZ-80?

The DCS circuit in the AD9216BCPZ-80 actively conditions incoming CLK_A and CLK_B signals to produce internally generated clocks with near-50% duty cycle, regardless of input duty cycle (down to 30%/70%). This preserves SNR and SFDR performance without requiring external clock-shaping circuitry, simplifying system timing design.

Can both channels of the AD9216BCPZ-80 operate at different sampling rates?

Yes. The AD9216BCPZ-80 provides independent CLK_A and CLK_B inputs, allowing asynchronous operation. Each channel can be clocked at different frequencies within the 10–80 MSPS range, and individual power-down (PWDN_A/PWDN_B) and output enable (OEB_A/OEB_B) controls permit flexible channel gating and sequencing.

What is the purpose of the MUX_SELECT pin on the AD9216BCPZ-80?

The MUX_SELECT pin configures the AD9216BCPZ-80 for multiplexed output mode, where both Channel A and Channel B data are time-division multiplexed onto a single 10-bit bus. When asserted, it enables interleaved output of A/B samples, reducing PCB trace count and interface complexity in resource-constrained systems.
