Product details
Overview
AD9262BCPZ from Analog Devices is a dual-channel, 16-bit continuous-time sigma-delta analog-to-digital converter (ADC) with 2.5 MHz input bandwidth, 30–160 MSPS output data rate, 83 dB SNR at 10 MHz input, 1 kΩ differential input impedance, and 1.8 V analog supply operation. It serves as the front-end digitizer in quadrature baseband receivers for wireless infrastructure.
For engineers reviewing the AD9262BCPZ datasheet, AD9262BCPZ pinout, AD9262BCPZ application, or AD9262BCPZ equivalent, this page delivers verified specifications, validated pin functions, confirmed industrial-temperature operation (−40°C to +85°C), exact LFCSP-64 package mapping, and two rigorously cross-referenced alternative parts for direct signal chain substitution.
Technical Context
The AD9262BCPZ implements a fifth-order continuous-time Σ-Δ modulator running at 640 MSPS with 32× oversampling, enabling high alias rejection without external antialiasing filters. Its passive resistive input interface eliminates driver amplifier requirements while maintaining 2.5 MHz real-bandwidth performance.
On-chip digital blocks include decimation filters with programmable passband transition (2.5 MHz), sample rate conversion, integrated PLL clock multiplier, dc and quadrature error correction, and selectable output data format (offset binary/Gray/twos complement). All operate under single 1.8 V AVDD and flexible 1.8–3.3 V DRVDD.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - guarantees full-scale linearity and ENOB ≥13.5 bits up to 8.4 MHz input frequency. |
| Analog Input Bandwidth | 2.5 MHz - defines maximum usable real-signal bandwidth for the AD9262BCPZ variant; distinct from -5 and -10 versions. |
| SNR | 83 dB at 10 MHz input - measured dynamic range enabling high-fidelity digitization of wideband IF signals. |
| SFDR | −87 dBc at 10 MHz input - quantifies spurious-free operation critical for multicarrier receiver applications. |
| Power Consumption | 538.5 mW typical (PLL disabled) - enables thermal design within 64-lead LFCSP's θJA = 21.2°C/W limit. |
| Input Impedance | 1 kΩ differential - simplifies anti-alias filter design and relaxes driver amplifier slew-rate requirements. |
| Operating Temperature | −40°C to +85°C - qualified for industrial and outdoor wireless base station environments. |
Pinout & Package
The AD9262BCPZ is housed in a 64-lead LFCSP (CP-64-4) package with exposed thermal pad (Pin 65) requiring solder connection to PCB ground plane for thermal and electrical integrity.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, sigma-delta ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9262BCPZ-5 | 5 MHz analog input bandwidth; higher SNR degradation above 2.4 MHz; identical pinout and SPI register map. | Required for wider IF bandwidths (e.g., multicarrier GSM/EDGE with 4.2 MHz tone spacing). | Select AD9262BCPZ-5 only if system IF bandwidth exceeds 2.5 MHz; otherwise AD9262BCPZ minimizes power (538.5 mW vs. 601.5 mW) and simplifies filter design. |
| AD9643BCPZ-150 | Pipelined 14-bit ADC; 150 MSPS; no integrated decimation or QEC; requires external clock clean-up and calibration. | Used where lower latency (<100 ns) and higher throughput outweigh need for on-chip filtering and correction. | Choose AD9643BCPZ-150 for time-critical applications like real-time beam steering; AD9262BCPZ remains optimal for RF receiver chains prioritizing dynamic range and integration. |
Compared with AD9262BCPZ-5 and AD9643BCPZ-150, the AD9262BCPZ uniquely balances 2.5 MHz bandwidth, 83 dB SNR, integrated QEC, and 538.5 mW power-making it the lowest-risk choice for cost-sensitive, thermally constrained quadrature receivers where external calibration is impractical.

FAQ
What is the analog input bandwidth of the AD9262BCPZ?
The AD9262BCPZ has a guaranteed 2.5 MHz analog input bandwidth, as specified in Table 1 of the Rev. A datasheet. This distinguishes it from the AD9262BCPZ-5 (5 MHz) and AD9262BCPZ-10 (10 MHz) variants. Bandwidth is defined by the −3 dB point of the on-chip decimation filter's passband transition, which is fixed at 2.5 MHz for this part number.
Does the AD9262BCPZ require an external driver amplifier?
No, the AD9262BCPZ does not require an external driver amplifier due to its 1 kΩ differential resistive input impedance and passive input structure. The datasheet explicitly states this feature reduces or eliminates driver amplifier requirements, simplifying front-end design for baseband and IF sampling applications.
What power supplies does the AD9262BCPZ use?
The AD9262BCPZ uses four independent supplies: AVDD = 1.8 V (analog core), CVDD = 1.8 V (clock circuitry), DVDD = 1.8 V (digital logic), and DRVDD = 1.8 V to 3.3 V (output driver level). Supply current values are specified per rail in Table 1, with total power consumption at 538.5 mW typical (PLL disabled).
How is quadrature error corrected in the AD9262BCPZ?
The AD9262BCPZ incorporates an integrated dc and quadrature estimation block that continuously measures and corrects gain and phase mismatch between Channel A and Channel B. This correction occurs digitally within the ADC's signal path and is applied before data output, eliminating the need for external calibration firmware or hardware.
What package type and thermal specifications apply to the AD9262BCPZ?
The AD9262BCPZ is supplied in a 64-lead LFCSP (CP-64-4) package with exposed thermal pad (Pin 65). Its thermal resistance is θJA = 21.2°C/W and θJC = 1.1°C/W when the exposed pad is soldered to the PCB ground plane-a mandatory requirement for reliability and thermal performance per datasheet Note 1.
