Product details
Overview
AD9601-250EBZ from Analog Devices is a 10-bit, 250 MSPS analog-to-digital converter (ADC) with CMOS digital outputs, 700 MHz full-power analog bandwidth, and integrated track-and-hold and on-chip reference. It operates from a single 1.8 V supply and supports offset binary, twos complement, or Gray code output formatting - used in broadband communications test equipment for high-fidelity IF sampling.
For engineers reviewing the AD9601-250EBZ datasheet, AD9601-250EBZ pinout, AD9601-250EBZ application, or AD9601-250EBZ equivalent, key selection criteria include SNR (59.4 dBFS @ 70 MHz), power dissipation (322 mW @ 250 MSPS), interleaved/dual-port output mode support, clock duty cycle stabilization, and SPI-configurable input voltage range (1.0–1.5 V).
Technical Context
The AD9601-250EBZ implements a pipelined switched-capacitor ADC architecture with digital error correction logic and a front-end differential sample-and-hold amplifier. Sampling occurs on the rising edge of the differential clock input, and the core supports both single-port (250 MHz) and demultiplexed dual-port (2 × 125 MHz) output modes.
It integrates an internal differential voltage reference generating ±0.625 V for a 1.25 V p-p full-scale span, programmable via SPI. The analog input stage features self-biasing to ~1.4 V common-mode and accepts differential signals up to 700 MHz bandwidth, with CML-compatible input bias control via the CML pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit - defines quantization granularity and dynamic range for baseband/IF digitization. |
| Max Sample Rate | 250 MSPS - enables Nyquist sampling of signals up to 125 MHz or undersampling of IFs in second/fourth Nyquist zones. |
| SNR @ 70 MHz | 59.4 dBFS - determines minimum detectable signal level in wideband receiver applications. |
| Full-Power Bandwidth | 700 MHz - supports high-frequency IF sampling without external anti-alias filtering degradation. |
| Power Dissipation | 322 mW @ 250 MSPS - enables thermal management in dense FPGA-ADC interface designs. |
| Input Voltage Range | Programmable 1.0–1.5 V p-p - allows optimization for varying driver output swing and noise floor trade-offs. |
| Digital Output Interface | CMOS-compatible, single or interleaved port - directly interfaces with Xilinx/Kintex or Intel/Arria FPGA I/O banks at 1.8 V. |
Pinout & Package
The AD9601-250EBZ evaluation board implements the AD9601 IC in a 56-lead LFCSP package (CP-56-2), with exposed paddle soldered to AGND. Pin functions are defined per the AD9601 silicon die layout and validated in the Rev. 0 datasheet Figure 4 and Table 7.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN+, VIN− | Differential analog input pair | Accepts ac- or dc-coupled RF/IF signals; requires matched source impedance for optimal common-mode rejection. |
| CLK+, CLK− | Differential clock inputs | Accept LVDS/LVPECL/CMOS clocks; internal bias eliminates need for external termination resistors. |
| DA0–DA9, DB0–DB9 | CMOS digital output data bits | Port A (DAx) and Port B (DBx) support single-port (250 MHz) or interleaved (2 × 125 MHz) output timing. |
| DCO+, DCO− | Data clock output pair | Provides synchronous edge-aligned clock for FPGA capture; critical for setup/hold timing closure. |
| OVRA, OVRB | Overrange flag outputs | Indicate saturation on respective ports - used for automatic gain control or clipping detection in real-time systems. |
| SDIO/DCS, SCLK/DFS, CSB | SPI serial interface pins | Enable runtime configuration of output format, power modes, gain, and test patterns without FPGA reconfiguration. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip reference & track-and-hold | Eliminates external reference ICs and discrete hold capacitors - reduces BOM count and layout sensitivity. |
| Programmable input voltage range | Enables system-level optimization between driver headroom and ADC noise floor across multiple signal chain configurations. |
| Serial port control (SPI) | Allows dynamic reconfiguration of output coding, power-down, and test pattern generation during operation - essential for adaptive receivers. |
| Integrated clock duty cycle stabilizer | Compensates for duty cycle distortion in low-jitter clock sources - preserves aperture jitter performance without external circuitry. |
| Single 1.8 V supply operation | Simplifies power delivery by unifying analog and digital rail requirements - reduces DC/DC converter count and PCB layer count. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9626-250EBZ | 12-bit resolution, same 250 MSPS rate, identical pinout and package, higher SNR (64.2 dBFS @ 70 MHz), higher power (520 mW) | Better ENOB (10.4 bits) suits demanding wideband spectrum analysis; not drop-in due to higher current draw and thermal load | Select AD9626-250EBZ when >10-bit ENOB is required and power/thermal budget permits. |
| ADS52J90IRGCT | 10-bit, 250 MSPS, JESD204B serial output (not parallel CMOS), 1.8 V supply, lower power (240 mW), no on-chip reference | Reduces FPGA pin count via serialized interface but requires JESD204B PHY and deterministic latency management | Select ADS52J90IRGCT when FPGA resources are constrained and JESD204B infrastructure is already deployed. |
Compared with AD9601-250EBZ, AD9626-250EBZ delivers 4.8 dB higher SNR at identical speed but increases power by 62%; ADS52J90IRGCT trades parallel CMOS simplicity for JESD204B scalability and 25% lower power, albeit with added protocol complexity and external reference dependency.

FAQ
What is the maximum analog input frequency supported by the AD9601-250EBZ?
The AD9601-250EBZ has a full-power analog bandwidth of 700 MHz, meaning it maintains specified dynamic performance (e.g., SNR ≥59.4 dBFS) for input signals up to 700 MHz. This enables direct sampling of IF signals in the second and third Nyquist zones - for example, 170 MHz inputs at 250 MSPS - without significant amplitude or phase distortion from the input buffer.
Does the AD9601-250EBZ require external decoupling capacitors on its AVDD and DRVDD supplies?
Yes, the AD9601-250EBZ requires external decoupling: 10 µF bulk + 0.1 µF ceramic capacitors placed near each AVDD and DRVDD pin per the AD9601 Rev. 0 datasheet Layout Considerations section. Although the on-chip reference eliminates *external reference decoupling*, analog and digital supply rails still demand local high-frequency bypassing to suppress switching noise and maintain SNR.
Can the AD9601-250EBZ operate in interleaved (dual-port) mode without SPI configuration?
No - interleaved mode must be enabled via SPI register write (address 0x08, bit 0 = 1). The AD9601-250EBZ powers up in single-port mode by default. Hardware pin strapping is not supported; all functional modes including output format, power-down, and duty cycle stabilization are controlled exclusively through the serial port interface.
What is the latency of the AD9601-250EBZ, and is it deterministic?
The AD9601-250EBZ exhibits fixed 6-clock-cycle latency from sample clock edge to valid output data, confirmed in both single-port and interleaved modes per Table 4 of the datasheet. This deterministic latency enables precise time-of-flight calculations in radar and synchronized multi-channel acquisition in test equipment using the AD9601-250EBZ.
Is the AD9601-250EBZ pin-compatible with other members of the AD96xx family?
The AD9601-250EBZ shares the same 56-lead LFCSP footprint and pinout with the AD9626-250 (12-bit variant), enabling hardware reuse across resolution tiers. However, it is *not* pin-compatible with AD9649 (14-bit, 80 MSPS) or AD9680 (14-bit, 1 GSPS), which use different packages and signal assignments - only the AD9626 series qualifies as pin-compatible per Product Highlights Section 5.
