Product details
Overview
AD9216BCPZ-65 from Analog Devices is a dual, 10-bit, 65 MSPS analog-to-digital converter (ADC) fabricated in advanced CMOS, featuring pipelined architecture with error correction, differential input (300 MHz bandwidth), and integrated voltage reference. It operates from a single 3.0 V analog supply and delivers 56.6 dBc SNR at Nyquist (32 MHz) and −80 dB crosstalk, targeting IF sampling in communications receivers and ultrasound front-ends.
For engineers reviewing the AD9216BCPZ-65 datasheet, AD9216BCPZ-65 pinout, AD9216BCPZ-65 application, or AD9216BCPZ-65 equivalent, key selection considerations include its dual-channel interleaving capability, clock duty cycle stabilizer (DCS), offset binary/twos complement output format, shared vs. independent reference mode control, and LFCSP-64 package thermal performance for high-density mixed-signal PCBs.
Technical Context
The AD9216BCPZ-65 employs a multistage differential pipelined ADC architecture with on-chip error correction logic to guarantee 10-bit accuracy and no missing codes across −40°C to +85°C. Its dual sample-and-hold amplifiers support simultaneous sampling with <−80 dB channel crosstalk up to 70 MHz input frequency.
It features dual single-ended clock inputs (CLK_A/CLK_B), a programmable clock duty cycle stabilizer (DCS), and flexible digital output control via OEB_A/OEB_B and PDWN_A/PDWN_B pins. Output data format (offset binary or twos complement) is selected by DFS, while reference sharing between channels is controlled by SHARED_REF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit - guarantees monotonic transfer function and no missing codes over full industrial temperature range. |
| Max Sample Rate | 65 MSPS - supports Nyquist-limited IF sampling up to ~32 MHz with validated AC performance. |
| SNR @ Nyquist | 56.6 dBc (typ) - defines usable dynamic range for baseband or IF digitization at maximum rate. |
| Analog Input BW | 300 MHz (3 dB) - enables wideband signal capture including harmonics and multi-carrier waveforms. |
| Crosstalk | < −80 dB - ensures minimal inter-channel interference in time-interleaved or parallel processing systems. |
| Power Consumption | 255 mW total (100 mW AVDD + 15 mW DRVDD per channel) - optimized for portable or thermally constrained instrumentation. |
| Aperture Jitter | 0.5 ps rms - limits sampling uncertainty, critical for high-frequency signal fidelity and ENOB retention. |
| Differential Input Range | 2.0 V p-p (with 1.0 V internal reference) - simplifies front-end driver design and supports DC-coupled architectures. |
Pinout & Package
AD9216BCPZ-65 is housed in a Pb-free, 64-lead LFCSP package (9 mm × 9 mm, 0.8 mm height), optimized for low-inductance analog/digital partitioning and thermal dissipation (θJA = 26.4°C/W on 4-layer board). Ground pins (AGND, DRGND) must be tied to a common ground plane per layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN+_A / VIN−_A VIN+_B / VIN−_B |
Differential analog inputs (Ch A & Ch B) | Accept 2.0 V p-p differential signals; support single-ended operation with external bias; 2 pF input capacitance requires careful driver matching. |
| CLK_A / CLK_B | Independent encode clocks per channel | Enable asynchronous or synchronized dual-channel sampling; duty cycle stabilizer (DCS) mitigates timing skew from non-50% clocks. |
| OEB_A / OEB_B | Output enable (active low) | Places respective 10-bit data buses (D0–D9) into high-impedance state - essential for multiplexed bus sharing or power sequencing. |
| PDWN_A / PDWN_B | Channel power-down control (active high) | Reduces power to static output mode (not Hi-Z); allows dynamic channel gating without reinitialization overhead. |
| DFS | Data format select | Low = offset binary; high = twos complement - determines sign interpretation in DSP/FPGA interface logic. |
| SHARED_REF | Reference topology control | High = shared VREF between channels (improves gain matching to ±0.1% FSR); low = independent references (±0.3% FSR matching). |
Key Features
| Feature | Design Value |
|---|---|
| Dual pipelined ADC with error correction | Guarantees 10-bit linearity and no missing codes at 65 MSPS across −40°C to +85°C - eliminates post-calibration in production systems. |
| Integrated clock duty cycle stabilizer (DCS) | Compensates for clock duty cycle variation outside 40–60%, preserving SNR/SFDR without external clock conditioning circuitry. |
| Configurable reference architecture | SHARED_REF pin selects between matched-gain (±0.1% FSR) or isolated-channel (±0.3% FSR) operation - supports both precision metrology and independent signal paths. |
| Low-power 3 V operation | 255 mW total at 65 MSPS (vs. 330 mW at 105 MSPS) - enables battery-powered handheld scopes and portable medical devices. |
| 300 MHz analog input bandwidth | Supports direct RF sampling of L-band signals and wideband IFs without external anti-alias filtering - reduces BOM count and board area. |
Applications
| Ultrasound Beamforming | IF Sampling in 3G/LMDS Receivers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9238BCPZ-65 | 12-bit resolution, same 64-lead LFCSP package and pinout; higher 74 dBc SFDR but lower 65 MSPS max rate. | Better dynamic range for precision instrumentation; less suitable for wideband IF where 10-bit ENOB suffices. | Select AD9238BCPZ-65 when ENOB > 11.5 bits required at 30 MHz; AD9216BCPZ-65 preferred for cost-sensitive, bandwidth-constrained designs. |
| AD9248BCPZ-65 | 14-bit resolution, identical footprint and pin compatibility; 65 MSPS max rate, but higher 300 mW power and reduced analog bandwidth (200 MHz). | Higher resolution for spectral analysis; trade-off includes greater thermal load and narrower input frequency support. | Choose AD9248BCPZ-65 for DC-coupled sensor digitization needing 14-bit linearity; AD9216BCPZ-65 better for RF/IF where bandwidth and power dominate. |
Compared with AD9238BCPZ-65 and AD9248BCPZ-65, the AD9216BCPZ-65 delivers optimal balance of 300 MHz analog bandwidth, 0.5 ps aperture jitter, and 255 mW power - making it uniquely suited for wideband, low-latency, thermally constrained dual-channel digitization where 10-bit resolution meets system SNR requirements.

FAQ
What is the guaranteed operating temperature range for AD9216BCPZ-65?
The AD9216BCPZ-65 is specified over the industrial temperature range of −40°C to +85°C. All DC and AC specifications - including SNR, INL, DNL, and crosstalk - are guaranteed across this range when operated within absolute maximum ratings and with proper decoupling. The LFCSP package's thermal resistance (θJA = 26.4°C/W) supports reliable operation under continuous 65 MSPS conversion in enclosed enclosures.
Does AD9216BCPZ-65 require an external voltage reference?
No, AD9216BCPZ-65 integrates a precision 1.0 V voltage reference with ±2 mV output error and ±15 ppm/°C drift. It can operate fully self-contained using the internal reference (VREF pin configured as output), or accept an external 1.0 V reference for improved stability. The SENSE pin configures reference mode, and REFT_A/REFB_A pins provide differential reference inputs for Channel A when external referencing is used.
How does the clock duty cycle stabilizer (DCS) function in AD9216BCPZ-65?
The DCS circuit in AD9216BCPZ-65 actively corrects non-50% clock duty cycles on CLK_A and CLK_B inputs, maintaining ADC performance (SNR/SFDR) across 30–70% duty cycle range. When DCS is enabled (DCS pin high), internal circuitry reshapes the clock edge timing without adding latency. This eliminates need for external duty cycle correction ICs in systems using crystal oscillators or PLLs with asymmetric outputs.
Can AD9216BCPZ-65 operate with single-ended analog inputs?
Yes, AD9216BCPZ-65 supports single-ended analog inputs via VIN+_A/VIN−_A and VIN+_B/VIN−_B pins. Each channel's SHA accepts either differential (recommended for noise rejection) or single-ended drive with appropriate DC biasing. Input common-mode voltage must be set to AVDD/2 (1.5 V) using external resistive dividers or op-amp level-shifting circuits; the 2 pF input capacitance requires careful driver impedance matching to avoid bandwidth degradation.
What is the pipeline latency of AD9216BCPZ-65, and how does it affect system timing?
AD9216BCPZ-65 has a fixed pipeline latency of 6 clock cycles from CLK rising edge to valid output data. This deterministic delay enables precise trigger-to-acquisition timing in oscilloscopes and synchronized sampling in multi-ADC systems. Latency remains constant across all sample rates (10–65 MSPS) and temperature conditions, simplifying FPGA-based data capture logic and eliminating need for variable delay compensation in real-time processing pipelines.
