Product details
Overview
AD9262BCPZ-10 from Analog Devices is a dual-channel, 16-bit continuous-time sigma-delta analog-to-digital converter (ADC) optimized for high-dynamic-range quadrature signal acquisition. It delivers 82.6 dB SNR and −93 dBc SFDR at 8.4 MHz input with 10 MHz analog bandwidth, operates on 1.8 V analog supply, consumes 600 mW, and targets baseband receivers in LTE and W-CDMA infrastructure.
For engineers reviewing the AD9262BCPZ-10 datasheet, AD9262BCPZ-10 pinout, AD9262BCPZ-10 application, or AD9262BCPZ-10 equivalent, key selection considerations include its 10 MHz input bandwidth variant, integrated dc/quadrature correction, 64-lead LFCSP package, 30–160 MSPS output data rate, and support for 1.8 V to 3.3 V digital I/O voltage.
Technical Context
The AD9262BCPZ-10 implements a 32× oversampled fifth-order continuous-time Σ-Δ modulator running at 640 MSPS, paired with on-chip decimation filters and sample rate converters to produce user-configurable output rates from 30 to 160 MSPS. Its resistive 1 kΩ differential input relaxes driver amplifier requirements and reduces external antialiasing filter complexity.
It integrates an integer-N PLL clock multiplier, on-chip 0.5 V reference, dc and quadrature error estimation blocks for inter-channel gain/phase mismatch correction, and supports offset binary, Gray code, or twos complement output formats with interleaved A/B channel data on a shared 16-bit bus.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - guarantees no missing codes over full industrial temperature range (−40°C to +85°C). |
| Analog Input Bandwidth | 10 MHz - defines maximum usable signal frequency before −3 dB roll-off; specific to AD9262BCPZ-10 variant. |
| SNR @ 8.4 MHz | 82.6 dB - measured at 25°C, −2 dBFS input, 40 MSPS output rate; enables high-fidelity RF baseband digitization. |
| SFDR @ 8.4 MHz | −104.1 dBc - spurious-free dynamic range at full-scale two-tone input; critical for multicarrier receiver linearity. |
| Power Consumption | 600 mW - total power at 1.8 V AVDD/CVDD/DVDD, DRVDD = 1.8 V, PLL disabled; includes analog and digital sections. |
| Input Impedance | 1 kΩ differential - passive, resistor-based input structure eliminates need for active driver amplifiers in many designs. |
| Output Data Rate | 30–160 MSPS - programmable via decimation ratio; supports flexible interface timing to FPGA or ASIC logic. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, high-resolution ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9265BCPZ-125 | 16-bit, 125 MSPS pipelined ADC; no Σ-Δ architecture; requires external antialiasing filter; higher power (1.2 W). | Targets wider instantaneous bandwidth (>60 MHz) but lacks integrated QEC and dc correction. | Choose when absolute speed >100 MSPS is required and external calibration infrastructure exists. |
| AD9643BCPZ-250 | 14-bit, 250 MSPS pipelined ADC; supports JESD204B interface; no on-chip decimation or PLL. | Designed for high-throughput backhaul and MIMO systems where raw throughput outweighs dynamic range per MHz. | Prefer for FPGA-based systems needing serialized high-speed links and lower latency than Σ-Δ processing chain. |
Compared with AD9265BCPZ-125 and AD9643BCPZ-250, the AD9262BCPZ-10 offers superior SNR/SFDR within its 10 MHz band, integrated signal conditioning, and lower power-but trades off maximum sample rate and digital interface flexibility.

FAQ
What is the analog input bandwidth specification for AD9262BCPZ-10?
The AD9262BCPZ-10 has a guaranteed analog input bandwidth of 10 MHz, as confirmed in Table 1 (DC Specifications) and Figure 25 of the Rev. A datasheet. This distinguishes it from the AD9262BCPZ-5 (5 MHz) and AD9262BCPZ (2.5 MHz) variants. The 10 MHz bandwidth supports wideband LTE and multicarrier GSM applications without external filtering.
Does AD9262BCPZ-10 support interleaved dual-channel output?
Yes, the AD9262BCPZ-10 supports interleaved output mode, allowing Channel A and Channel B data to be multiplexed onto a single 16-bit bus. This is implemented via dedicated control registers and simplifies PCB routing and FPGA interface logic compared to separate parallel buses for each channel.
What is the typical SNR performance of AD9262BCPZ-10 at 8.4 MHz input frequency?
The AD9262BCPZ-10 achieves 82.6 dB SNR at fIN = 8.4 MHz, as measured under standard conditions (−2 dBFS input, 40 MSPS output rate, 25°C). This value is explicitly documented in Figure 18 of the Rev. A datasheet and reflects its optimized 10 MHz bandwidth variant's performance in high-frequency baseband capture.
How does the integrated dc and quadrature correction function in AD9262BCPZ-10?
The AD9262BCPZ-10 incorporates a dedicated hardware block that continuously estimates and corrects gain and phase mismatch between its two ADC channels. This correction occurs in real time and is essential for achieving high image rejection in direct-conversion receivers-eliminating the need for external calibration routines or post-processing compensation.
What package type and thermal requirements apply to AD9262BCPZ-10?
The AD9262BCPZ-10 uses a 64-lead LFCSP package (CP-64-4) with an exposed thermal pad (EPAD) that must be soldered to the PCB ground plane. Per Table 7, this achieves θJC = 1.1°C/W. Failure to connect the EPAD compromises thermal performance and may violate junction temperature limits under sustained operation.
