Product details
Overview
AD9204BCPZ-80 from Analog Devices is a dual-channel, 10-bit, 80 MSPS analog-to-digital converter operating from a single 1.8 V analog supply with separate 1.8 V–3.3 V digital output drivers. It features a 700 MHz differential analog input bandwidth, on-chip voltage reference and sample-and-hold, and supports offset binary/gray/twos complement data formats. It is used in I/Q demodulation systems requiring high dynamic range at RF frequencies up to 200 MHz.
For engineers reviewing the AD9204BCPZ-80 datasheet, AD9204BCPZ-80 pinout, AD9204BCPZ-80 application, or AD9204BCPZ-80 equivalent, key selection criteria include its 61.0 dBFS SNR at 200 MHz input, 73 dBc SFDR at same frequency, 9-cycle pipeline latency, DNL of ±0.11 LSB (typ), and RoHS-compliant 64-lead LFCSP package with exposed paddle grounding requirement.
Technical Context
The AD9204BCPZ-80 employs a multistage differential pipeline architecture with output error correction logic to guarantee 10-bit accuracy and no missing codes across −40°C to +85°C. Its patented sample-and-hold maintains performance up to 200 MHz input while enabling low-power operation at 63 mW per channel.
Dual independent ADC cores share a differential clock input (CLK+/CLK−) supporting CMOS/LVDS/LVPECL levels, with optional duty cycle stabilizer (DCS) and integer 1-to-8 clock divider. Digital outputs are CMOS-compatible, with programmable DCO/data alignment and built-in deterministic/pseudorandom test pattern generation via SPI.

Pinout & Package
The AD9204BCPZ-80 is housed in a 64-lead RoHS-compliant LFCSP package (CP-64-17) with an exposed paddle that must be soldered to AGND for thermal, noise, and mechanical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (exposed paddle) | Primary ground reference | Only chip ground connection; mandatory soldering to PCB AGND plane for thermal dissipation and noise control. |
| CLK+, CLK− | Differential clock input | Accepts CMOS/LVDS/LVPECL; controls all internal conversion cycles; enables jitter-insensitive sampling. |
| VIN+A, VIN−A / VIN+B, VIN−B | Differential analog inputs | Two independent 700 MHz bandwidth channels; support 1–2 Vp-p differential input span with 0.9 V common-mode. |
| D0A–D9A, D0B–D9B | CMOS digital outputs | 10-bit parallel outputs per channel; MSB-aligned; support 1.8 V or 3.3 V logic levels via DRVDD supply. |
| DCOA, DCOB | Data clock outputs | Source-synchronous clocks for latch timing; programmable phase alignment relative to data edges. |
| SDIO/DCS, SCLK/DFS, CSB | SPI interface pins | Enable configuration of data format, clock divider, power modes, and test patterns without external logic. |
| PDWN, OEB | Power and output control | PDWN high enters 2.2 mW power-down; OEB low enables outputs, high places them in high-impedance state. |
Key Features
| Feature | Design Value |
|---|---|

FAQ
What is the maximum analog input frequency supported by the AD9204BCPZ-80?
The AD9204BCPZ-80 supports analog input frequencies up to 200 MHz while maintaining specified AC performance, including 61.0 dBFS SNR and 73 dBc SFDR. Its 700 MHz analog input bandwidth ensures minimal amplitude roll-off and phase distortion across this range, making it suitable for direct RF sampling in L-band applications.
Does the AD9204BCPZ-80 require an external voltage reference?
No, the AD9204BCPZ-80 includes an on-chip voltage reference with 0.981–1.005 V output and ±2 ppm/°C drift. An external reference may be used via the VREF pin, but the internal reference eliminates BOM cost and layout complexity in most applications where ±0.5% gain accuracy suffices.
How is channel synchronization achieved between the two ADCs in the AD9204BCPZ-80?
The AD9204BCPZ-80 uses a shared differential clock input (CLK+/CLK−) and internal synchronous sampling architecture to ensure deterministic inter-channel timing. Both channels exhibit identical 9-cycle pipeline latency and sub-100 ps inter-channel skew, enabling coherent I/Q sampling without external deskew circuitry.
What digital output formats does the AD9204BCPZ-80 support?
The AD9204BCPZ-80 supports offset binary, gray code, and twos complement formats, selectable via SPI register configuration or static pin control (SCLK/DFS). This flexibility allows seamless interface with FPGAs implementing different arithmetic logic or legacy DSP architectures requiring specific coding conventions.
Can the AD9204BCPZ-80 operate with a 3.3 V digital supply while using a 1.8 V analog supply?
Yes, the AD9204BCPZ-80 separates analog (AVDD = 1.8 V) and digital output (DRVDD = 1.8 V to 3.3 V) supplies. With DRVDD = 3.3 V, it delivers CMOS-compatible outputs meeting 3.3 V logic thresholds (VOH ≥ 3.25 V, VOL ≤ 0.2 V), enabling direct interfacing with 3.3 V FPGAs or ASICs without level shifters.
