Product details
Overview
AD9246BCPZ-80 from Analog Devices is a 14-bit, 80 MSPS monolithic analog-to-digital converter with 1.8 V analog supply, differential input (650 MHz bandwidth), on-chip voltage reference, and clock duty cycle stabilizer. It delivers SNR = 71.9 dBc at 2.4 MHz and SFDR = 85 dBc at 70 MHz input, targeting IF sampling in communications receivers and ultrasound equipment.
For engineers reviewing the AD9246BCPZ-80 datasheet, AD9246BCPZ-80 pinout, AD9246BCPZ-80 application, or AD9246BCPZ-80 equivalent, key selection criteria include guaranteed no missing codes over −40°C to +85°C, flexible 1 V p-p to 2 V p-p analog input range, offset binary/Gray/twos complement output formatting, and support for CMOS/LVDS/LVPECL clock inputs.
Technical Context
The AD9246BCPZ-80 employs a multistage differential pipeline architecture with output error correction logic to ensure 14-bit accuracy and no missing codes across temperature. Its sample-and-hold amplifier supports true differential inputs up to 225 MHz and enables single-ended operation via user-selectable common-mode bias.
A dedicated duty cycle stabilizer (DCS) maintains ADC performance across wide clock duty cycle variations (e.g., 30%–70%), while the serial port interface (SPI-compatible) allows runtime configuration of data format, DCS enable/disable, power-down mode, and reference selection without external components.

Pinout & Package
The AD9246BCPZ-80 is housed in a 48-lead LFCSP_VQ package (7 mm × 7 mm × 0.85 mm) with exposed thermal pad (Pin 0) soldered to AGND for optimal thermal dissipation and noise immunity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK+, CLK− | Differential clock input | Accepts CMOS/LVDS/LVPECL; internal bias enables single-supply clocking without external termination resistors. |
| VIN+, VIN− | Differential analog input | 650 MHz bandwidth; supports 1 V p-p to 2 V p-p full-scale range with programmable common-mode level via CML pin. |

| DCO | Data clock output | Source-synchronous clock aligned to data edges; eliminates timing skew in high-speed digital interface design. |
| 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 power to 1.8 mW; enables rapid wake-up (<350 μs) for burst-mode acquisition in portable test equipment. |
Key Features
| Feature | Design Value |

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-80 | 12-bit resolution, same 48-lead LFCSP_VQ package and pinout; lower power (220 mW), reduced SFDR (75 dBc @ 70 MHz). | Lower dynamic range suitable for non-critical instrumentation where 12-bit ENOB suffices. | Select when cost and power are prioritized over SNR/SFDR and system-level spurious performance is less demanding. |
| ADS5272IPFP | Texas Instruments 12-bit, 80 MSPS ADC; LVDS outputs only; requires external reference; higher typical power (450 mW). | Lacks DCS and built-in test patterns; requires more external components and layout effort for clock conditioning. | Choose if existing TI ecosystem integration (e.g., TMS320C6000 DSP interface) outweighs added BOM and layout complexity. |
Compared with AD9246BCPZ-80, AD9233BCPZ-80 offers drop-in migration path with identical footprint but trades 2 bits of resolution for lower cost and power, while ADS5272IPFP demands external reference and clock conditioning-increasing design risk and component count despite comparable sampling rate.

FAQ
What is the maximum analog input frequency supported by the AD9246BCPZ-80?
The AD9246BCPZ-80 features a 650 MHz analog input bandwidth, enabling accurate digitization of signals up to 225 MHz while maintaining specified SNR and SFDR performance. This supports undersampling architectures for IF frequencies in wireless receivers and harmonic imaging in ultrasound systems. The AD9246BCPZ-80 achieves 71.7 dBc SNR at 70 MHz input and retains usable ENOB (>11 bits) up to 170 MHz.
Does the AD9246BCPZ-80 require an external voltage reference?
No, the AD9246BCPZ-80 integrates a precision 1.0 V voltage reference with ±20 mV output error over temperature, eliminating the need for external reference components. The SENSE pin allows selection between internal reference mode and external reference mode, and REFT/REFB pins support differential reference configuration when higher accuracy is required. The AD9246BCPZ-80's on-chip reference reduces BOM count and layout area versus discrete reference solutions.
How does the clock duty cycle stabilizer (DCS) function in the AD9246BCPZ-80?
The AD9246BCPZ-80's DCS corrects for wide variations in input clock duty cycle (e.g., 30%–70%) without degrading SNR or SFDR, ensuring consistent sampling aperture timing. It operates transparently when enabled via SPI or SDIO/DCS pin, and maintains <0.1 ps rms aperture jitter. This allows use of low-cost crystal oscillators or FPGA-generated clocks without external duty cycle correction circuitry. The AD9246BCPZ-80's DCS is active by default in most configurations.
Can the AD9246BCPZ-80 interface directly with a 1.8 V FPGA I/O bank?
Yes, the AD9246BCPZ-80 supports 1.8 V digital output driver supply (DRVDD), producing VOH = 1.75 V and VOL = 0.2 V at 0.5 mA load-fully compatible with 1.8 V LVCMOS I/O standards. Its DCO output provides source-synchronous timing, and the 14-bit parallel bus eliminates serialization overhead. The AD9246BCPZ-80 also supports 3.3 V DRVDD for interfacing with legacy microcontrollers, offering seamless voltage-level flexibility.
Is the AD9246BCPZ-80 pin-compatible with other speed grades in the AD9246 family?
Yes, all AD9246 speed variants-including AD9246BCPZ-80, AD9246BCPZ-105, and AD9246BCPZ-125-share identical 48-lead LFCSP_VQ packaging and pinout. This enables hardware reuse across performance tiers: a single PCB layout can support 80/105/125 MSPS operation via firmware update and clock rate change. The AD9246BCPZ-80's pin compatibility simplifies inventory management and design scalability without layout revision.
