Product details
Overview
AD9233BCPZ-105 from Analog Devices is a 12-bit, 105 MSPS analog-to-digital converter (ADC) operating from a single 1.8 V analog supply with differential input bandwidth up to 650 MHz, SNR of 69.5 dBc at 70 MHz input, SFDR of 85 dBc, and DNL of ±0.15 LSB. It integrates an on-chip voltage reference and sample-and-hold amplifier, and is used in IF sampling for communications receivers and ultrasound equipment.
For engineers reviewing the AD9233BCPZ-105 datasheet, AD9233BCPZ-105 pinout, AD9233BCPZ-105 application, or AD9233BCPZ-105 equivalent, key selection considerations include its 105 MSPS sampling rate, 1.8 V analog supply compatibility, differential clock interface (LVDS/CMOS/LVPECL), data output clock (DCO), and serial port control for format and power configuration.
Technical Context
The AD9233BCPZ-105 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 patented sample-and-hold amplifier supports full-scale input frequencies up to 225 MHz and flexible analog input ranges (1 V p-p to 2 V p-p).
A duty cycle stabilizer (DCS) maintains ADC performance over wide clock duty cycle variations, while the serial port interface enables real-time configuration of data format (offset binary/Gray/twos complement), DCS enable, power-down mode, and reference selection - all without requiring external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit - guarantees monotonicity and no missing codes over full temperature range. |
| Sampling Rate | 105 MSPS - supports Nyquist-limited IF sampling up to ~52.5 MHz or undersampling of RF signals beyond 100 MHz. |
| SNR / SFDR | 69.5 dBc / 85 dBc at 70 MHz input - enables high-fidelity digitization of narrowband and wideband communication signals. |
| Analog Supply | 1.8 V AVDD - reduces system power and simplifies power rail design versus legacy 3.3 V or 5 V ADCs. |
| Differential Input BW | 650 MHz - allows direct sampling of L-band and S-band IFs without external amplification or filtering. |
| Power Consumption | 350 mW at 105 MSPS (DRVDD = 3.3 V) - balances performance and thermal budget in space-constrained embedded systems. |
| Input Range | 1 V p-p to 2 V p-p differential - configurable via external resistor network on SENSE/VREF pins for optimal dynamic range matching. |
Pinout & Package
The AD9233BCPZ-105 is housed in a 48-lead LFCSP (CP-48-5) package with exposed thermal pad (Pin 0 = AGND), optimized for high-frequency signal integrity and thermal dissipation (θJA = 26.4°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D0–D11 | Digital output data bus (LSB to MSB) | 12-bit parallel CMOS outputs compatible with 1.8 V to 3.3 V logic; timing referenced to DCO. |
| CLK+, CLK− | Differential clock input | Accepts LVDS, CMOS, or LVPECL; internal biasing enables single-ended drive; DCS corrects duty cycle distortion. |
| VIN+, VIN− | Differential analog input | 650 MHz bandwidth; supports ac-coupled or dc-coupled configurations; common-mode level set by CML pin. |
| DCO | Data clock output | Source-synchronous clock aligned to D0–D11 edges; eliminates setup/hold timing margin concerns at receiver. |
| SDIO/DCS, SCLK/DFS, CSB | 3-wire SPI interface | Configures data format, DCS enable, power-down, and reference mode; operates independently of conversion clock. |
| PDWN | Hardware power-down control | Reduces current to 1.8 mW; wake-up time <350 ms with 0.1 μF decoupling on REFT/REFB. |
| RBIAS | Reference bias resistor connection | Requires 10 kΩ to AGND to set internal reference current; critical for VREF stability and INL performance. |
Key Features
| Feature | Design Value |
|---|---|
| Single 1.8 V analog supply | Eliminates need for multiple analog rails; reduces BOM count and PCB area vs. dual-supply ADCs. |
| On-chip voltage reference | 1.0 V nominal output with ±20 mV error; removes external reference IC and associated layout sensitivity. |
| Programmable data format | Offset binary, Gray code, or twos complement selectable via SPI - simplifies FPGA interface logic design. |
| Duty cycle stabilizer (DCS) | Compensates for >30% clock duty cycle variation without SNR/SFDR degradation - relaxes clock source requirements. |
| Built-in test pattern generation | Enables production testing and system-level validation without external pattern generator hardware. |

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-125 | Higher sampling rate (125 MSPS); identical pinout, package, and feature set; 45 mW higher power at full rate. | Suitable where oversampling or wider Nyquist zone is required; same PCB layout but requires higher clock frequency and thermal management. | Select AD9233BCPZ-125 only if system demands >105 MSPS; otherwise AD9233BCPZ-105 offers optimal power/performance trade-off. |
| AD9246BCPZ-105 | 14-bit resolution, same 105 MSPS rate and LFCSP-48 package; pin-compatible per Product Highlights; higher SNR (74.5 dBc) but 550 mW power. | Used when ENOB >11.4 bits is mandatory (e.g., high-dynamic-range radar); requires tighter clock jitter control and larger power delivery network. | Choose AD9246BCPZ-105 for precision measurement applications needing extra 2 bits; AD9233BCPZ-105 remains preferred for cost- and power-sensitive designs. |
Compared with AD9233BCPZ-125 and AD9246BCPZ-105, the AD9233BCPZ-105 delivers the best balance of 12-bit fidelity, 105 MSPS throughput, and 350 mW power in a compact LFCSP - making it ideal for portable, thermally constrained, and cost-driven IF sampling systems.

FAQ
What is the maximum analog input frequency supported by the AD9233BCPZ-105?
The AD9233BCPZ-105 features a 650 MHz analog input bandwidth and supports full-scale input frequencies up to 225 MHz while maintaining specified SNR and SFDR performance. This enables direct undersampling of RF and IF signals in communications and radar applications without external amplification.
Does the AD9233BCPZ-105 require an external voltage reference?
No, the AD9233BCPZ-105 includes an on-chip 1.0 V voltage reference with ±20 mV output error over temperature. An external 10 kΩ resistor must be connected from RBIAS to AGND to bias the reference, but no external reference IC is needed - reducing BOM cost and layout complexity.
How does the duty cycle stabilizer (DCS) function in the AD9233BCPZ-105?
The DCS in the AD9233BCPZ-105 dynamically adjusts internal clock paths to compensate for duty cycle variations from 30% to 70%, preserving SNR and SFDR performance without requiring precise clock sources. It can be enabled/disabled via SPI or controlled by the SDIO/DCS pin in external mode.
What digital output formats does the AD9233BCPZ-105 support?
The AD9233BCPZ-105 supports three programmable output data formats: offset binary, Gray code, and twos complement - selected via the serial port interface (SPI). This flexibility simplifies interface design with FPGAs or ASICs that expect specific coding schemes for downstream processing.
Is the AD9233BCPZ-105 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 redesign, provided thermal and power delivery margins accommodate the higher-rate variants.
