Product details
Overview
AD9233BCPZ-80 from Analog Devices is a monolithic 12-bit, 80 MSPS analog-to-digital converter with 1.8 V analog supply, differential input (650 MHz bandwidth), on-chip voltage reference, and serial port interface. It delivers SNR = 69.5 dBc and SFDR = 85 dBc at 70 MHz input, supporting IF sampling in communications receivers and ultrasound equipment.
For engineers reviewing the AD9233BCPZ-80 datasheet, AD9233BCPZ-80 pinout, AD9233BCPZ-80 application, or AD9233BCPZ-80 equivalent, key selection criteria include its 80 MSPS sampling rate, 1.8 V AVDD operation, DNL = ±0.15 LSB, industrial temperature range (−40°C to +85°C), and LFCSP-48 package compatibility with evaluation board AD9233-EBZ.
Technical Context
The AD9233BCPZ-80 employs a multistage differential pipeline architecture with output error correction logic to guarantee 12-bit accuracy and no missing codes across −40°C to +85°C. Its differential sample-and-hold amplifier supports flexible analog input ranges (1 V p-p to 2 V p-p) and maintains performance up to 225 MHz input frequency.
A duty cycle stabilizer (DCS) compensates for clock duty cycle variations while preserving AC performance; digital outputs are configurable in offset binary, Gray code, or twos complement formats, synchronized by an embedded data output clock (DCO).

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9233BCPZ-105 | Higher 105 MSPS sampling rate; identical 12-bit resolution, pinout, and feature set | Required for wider IF bandwidths (>35 MHz) or higher Nyquist zones in spectrum analyzers | Select when system clock budget supports >80 MSPS and SNR/SFDR trade-offs at higher rates are acceptable |
| AD9246BCPZ-80 | 14-bit resolution, same 80 MSPS rate, pin-compatible LFCSP-48 package, but higher 495 mW power | Used where ENOB > 11.4 bits is mandatory-e.g., medical imaging quantization or high-fidelity radar pulse analysis | Choose for enhanced dynamic range at cost of +40% power and larger FPGA resource utilization |
Compared with AD9233BCPZ-105 and AD9246BCPZ-80, the AD9233BCPZ-80 offers optimal balance of 12-bit fidelity, 80 MSPS throughput, and 350 mW power-making it ideal for cost- and thermally constrained IF digitization where 14-bit resolution is unnecessary.

FAQ
What is the maximum analog input frequency supported by the AD9233BCPZ-80?
The AD9233BCPZ-80 features a 650 MHz analog input bandwidth and maintains specified SNR/SFDR performance up to 225 MHz input frequency. At 70 MHz, it achieves 69.5 dBc SNR and 85 dBc SFDR; performance degrades gradually beyond that, with 68.9 dBc SNR measured at 170 MHz. This enables undersampling of IF signals well above the 40 MHz Nyquist frequency of its 80 MSPS rate.
Does the AD9233BCPZ-80 require an external voltage reference?
No, the AD9233BCPZ-80 includes an on-chip 1.0 V voltage reference with ±20 mV output error over temperature. External reference is optional and enabled via the SENSE pin; when using the internal reference, REFT and REFB pins are left unconnected. This eliminates BOM cost and layout area for reference ICs in most applications.
How does the duty cycle stabilizer (DCS) function in the AD9233BCPZ-80?
The AD9233BCPZ-80's DCS circuit dynamically adjusts internal clock timing to maintain consistent aperture jitter (<0.1 ps rms) despite wide variations in input clock duty cycle (30%–70%). It operates automatically when enabled via SPI or external SDIO/DCS pin, ensuring full AC performance without requiring precision clock sources-critical for systems using PLL-based or crystal oscillator-derived clocks.
What digital output formats does the AD9233BCPZ-80 support?
The AD9233BCPZ-80 supports three programmable output data formats: offset binary, Gray code, and twos complement. Format selection is performed via the SPI interface (register 0x08, bit D2–D1) or hardware pins (SCLK/DFS and SDIO/DCS in external pin mode). All formats operate at full 80 MSPS with identical timing and drive strength.
Is the AD9233BCPZ-80 pin-compatible with other members of the AD9233 family?
Yes, all AD9233 speed grades-including AD9233BCPZ-80, AD9233BCPZ-105, and AD9233BCPZ-125-share identical 48-lead LFCSP (CP-48-5) packaging and pinout. This allows drop-in replacement across sampling rates without PCB modification, provided system clock, power, and thermal design accommodate the higher current draw of faster variants.
