Product details
Overview
AD9627ABCPZ-80 from Analog Devices is a dual-channel, 12-bit, 80 MSPS analog-to-digital converter with differential 650 MHz analog input bandwidth, 1.8 V analog supply operation, and CMOS or LVDS digital outputs. It integrates fast detect, signal monitor, and clock duty cycle stabilization for IF sampling up to 450 MHz in diversity radio and multimode receivers.
For engineers reviewing the AD9627ABCPZ-80 datasheet, AD9627ABCPZ-80 pinout, AD9627ABCPZ-80 application, or AD9627ABCPZ-80 equivalent, key selection considerations include its 80 MSPS sample rate, dual-channel SNR of 69.5 dBc at 70 MHz, 95 dB channel isolation, 1.8 V single-supply analog core, and SPI-configurable AGC support features.
Technical Context
The AD9627ABCPZ-80 employs a multistage differential pipelined ADC architecture with integrated error correction logic and on-chip sample-and-hold amplifiers. Its analog inputs support 1 Vp-p to 2 Vp-p differential ranges and maintain 69.5 dBc SNR up to 70 MHz input frequency.
It features a dedicated signal monitor block with serial output, four-bit fast detect for low-latency overrange indication, and an integer 1-to-8 clock divider with duty cycle stabilizer. Digital interface supports 1.8 V to 3.3 V CMOS or 1.8 V LVDS output drivers, and configuration uses a 3-wire SPI-compatible serial port.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit - delivers 12-bit quantization precision per channel with guaranteed no missing codes. |
| Sample Rate | 80 MSPS - fixed maximum conversion rate for this variant, enabling real-time digitization of wideband IF signals. |
| SNR @ 70 MHz | 69.5 dBc - measured with −1.0 dBFS input, defining usable dynamic range for communications band signals. |
| Analog Input Bandwidth | 650 MHz - supports high-frequency IF sampling up to 450 MHz without external filtering degradation. |
| Power Consumption | 495 mW (sine wave, DRVDD = 1.8 V) - enables compact thermal design in space-constrained radio front ends. |
| Channel Isolation | 95 dB - ensures minimal crosstalk between dual channels during simultaneous I/Q or diversity sampling. |
| Digital Output Interface | CMOS or LVDS - selectable via DRVDD voltage, allowing direct interfacing with FPGA I/O banks or ASIC receivers. |
Pinout & Package
AD9627ABCPZ-80 is housed in a 64-lead LFCSP (Lead Frame Chip Scale Package) with exposed paddle, rated for −40°C to +85°C industrial operation. Pin functions are defined for both CMOS and LVDS configurations; the table below reflects the CMOS pinout as specified in Figure 7 of Rev. B datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN+A / VIN–A | Differential analog input, Channel A | Accepts 650 MHz bandwidth differential signal; requires matched 100 Ω termination for optimal SNR. |
| VIN+B / VIN–B | Differential analog input, Channel B | Independent high-bandwidth input path; 95 dB isolation prevents coupling into Channel A. |
| CLK+ / CLK− | Differential clock input | Accepts CMOS/LVDS/LVPECL; internal bias enables single-ended drive with external termination. |
| D0A–D11A / D0B–D11B | 12-bit parallel CMOS data outputs | MSB-first, offset binary format; timing referenced to DCOA/DCOB with 12-cycle pipeline latency. |
| FD(0:3)A / FD(0:3)B | Fast detect magnitude bits | 4-bit coarse amplitude indicator per channel; <100 ns latency enables real-time AGC response. |
| SYNC | Multi-chip synchronization input | Aligns sampling phase across multiple AD9627 devices for coherent array or MIMO systems. |
| CSB / SCLK / SDIO | SPI serial interface | 3-wire control bus for configuring data format, power modes, reference, and signal monitor thresholds. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, 12-bit ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9627BCPZ-105 | Higher 105 MSPS sample rate; 750 mW power at 125 MSPS (not applicable); same 64-lead LFCSP package and pinout. | Supports wider instantaneous bandwidth (e.g., 40 MHz LTE channel + guard bands) but requires higher clock and power budget. | Select AD9627BCPZ-105 when system IF bandwidth exceeds 35 MHz and board-level power delivery supports +75 mW increase. |
| AD9640BCPZ-80 | 14-bit resolution, same 80 MSPS rate, pin-compatible LFCSP-64 package, but higher 950 mW power and 70 dBFS SNR at 70 MHz. | Targets higher dynamic range applications (e.g., radar pulse detection) where 2-bit ENOB improvement justifies 90% power increase. | Choose AD9640BCPZ-80 only if system SNR requirement exceeds 70 dBFS and thermal design accommodates doubled dissipation. |
Compared with AD9627BCPZ-105 and AD9640BCPZ-80, the AD9627ABCPZ-80 provides optimal balance of 12-bit fidelity, 80 MSPS throughput, and 495 mW power for cost-sensitive, thermally constrained communications receivers requiring proven 95 dB isolation and fast AGC support.

FAQ
What is the maximum analog input frequency supported by the AD9627ABCPZ-80?
The AD9627ABCPZ-80 supports analog input frequencies up to 450 MHz through IF sampling, enabled by its 650 MHz analog input bandwidth and proprietary differential input structure. This capability is validated in the datasheet's AC specifications and functional block diagram, and applies directly to the AD9627ABCPZ-80 variant as confirmed in the General Description section.
Does the AD9627ABCPZ-80 support LVDS output interface?
Yes, the AD9627ABCPZ-80 supports LVDS output interface when DRVDD is set to 1.8 V. The datasheet specifies differential output voltage (VOD) of 250–450 mV in ANSI mode and 150–280 mV in reduced swing mode, with output offset voltage (VOS) of 1.15–1.35 V - all confirmed for the AD9627ABCPZ-80 in Table 5 and Switching Specifications.
What is the pipeline latency of the AD9627ABCPZ-80 in CMOS mode?
The AD9627ABCPZ-80 exhibits a fixed 12-cycle pipeline latency in CMOS output mode, as specified in Table 6 (Switching Specifications-AD9627-80/AD9627-105). This deterministic latency enables precise timing alignment in FPGA-based digital downconverters and is identical for both Channel A and Channel B.
How does the fast detect feature operate on the AD9627ABCPZ-80?
The AD9627ABCPZ-80 provides four fast detect (FD) bits per channel (FD0–FD3) that deliver coarse input magnitude information with sub-100 ns latency. These bits are updated every sample period and can trigger immediate AGC response - a function explicitly documented for the AD9627ABCPZ-80 in the Product Highlights and General Description sections.
Is the AD9627ABCPZ-80 pin-compatible with other members of the AD9627 family?
Yes, the AD9627ABCPZ-80 shares the same 64-lead LFCSP package and pinout with AD9627BCPZ-105, AD9627BCPZ-125, and AD9627BCPZ-150, as stated in Product Highlight #7. This allows hardware reuse across sample rate variants, though performance parameters like power and AC specs differ per speed grade.
