Product details
Overview
AD9262BCPZ-5 from Analog Devices is a dual-channel, 16-bit continuous-time sigma-delta analog-to-digital converter (ADC) optimized for quadrature baseband sampling in communications receivers. It delivers 85 dB SNR and −87 dBc SFDR up to 10 MHz input bandwidth, operates with 1.8 V analog supply and 1.8–3.3 V digital output supply, consumes 600 mW, and supports 5 MHz real/10 MHz complex input bandwidth. It is used in W-CDMA and LTE direct-conversion receiver front-ends.
For engineers reviewing the AD9262BCPZ-5 datasheet, AD9262BCPZ-5 pinout, AD9262BCPZ-5 application, or AD9262BCPZ-5 equivalent, key selection considerations include its 5 MHz analog input bandwidth specification, integrated dc/quadrature correction for I/Q channel matching, 64-lead LFCSP package thermal performance, and SPI-configurable decimation filter settings for flexible output data rate (30–160 MSPS).
Technical Context
The AD9262BCPZ-5 implements a 32× oversampled fifth-order continuous-time Σ-Δ modulator running at 640 MSPS, with integrated low-pass decimation filters and sample rate converters that reduce output data rate to user-selectable 30–160 MSPS. Its passive resistive input impedance (1 kΩ differential) eliminates need for external driver amplifiers in many applications.
It incorporates on-chip PLL clock multiplier for internal 640 MHz clock generation, integrated voltage reference (500 mV), and hardware-based dc and quadrature error estimation blocks that correct gain/phase mismatch between Channel A and Channel B-critical for complex signal processing in zero-IF architectures.

FAQ
What is the analog input bandwidth specification for AD9262BCPZ-5?
The AD9262BCPZ-5 has a specified analog input bandwidth of 5 MHz (real) and 10 MHz (complex). This value is confirmed in Table 1 (DC Specifications) and Figure 10–15 of the Rev. A datasheet, where performance metrics are explicitly guaranteed over the full temperature range only for the AD9262BCPZ-5 variant. It defines the maximum frequency at which the device maintains specified SNR and SFDR performance without external filtering.
Does AD9262BCPZ-5 support interleaved dual-channel output mode?
Yes, the AD9262BCPZ-5 supports interleaved output mode, allowing Channel A and Channel B data to be multiplexed onto a single 16-bit bus. This capability is documented in the General Description section and functional block diagram (Figure 1), and reduces PCB routing complexity by halving the number of data traces required compared to independent parallel buses.
What power supply voltages does AD9262BCPZ-5 require?
The AD9262BCPZ-5 requires four independent supply rails: AVDD = 1.8 V (analog), DVDD = 1.8 V (digital core), DRVDD = 1.8 V to 3.3 V (output driver), and CVDD = 1.8 V (clock). These values are specified in Table 1 (DC Specifications) and Absolute Maximum Ratings (Table 6), with recommended operating ranges ensuring proper functionality across the industrial temperature range.
How does the integrated dc and quadrature correction work in AD9262BCPZ-5?
The AD9262BCPZ-5 incorporates dedicated hardware blocks that continuously estimate and correct dc offset and quadrature gain/phase mismatch between Channel A and Channel B. As described in the General Description and DC and Quadrature Error Correction section, this occurs in real time using internal calibration algorithms-no external processor or firmware intervention is needed, making it ideal for standalone I/Q receiver designs.
What is the typical SNR performance of AD9262BCPZ-5 at 1.2 MHz input frequency?
The AD9262BCPZ-5 achieves a typical SNR of 85.3 dB at fIN = 1.2 MHz, as measured with a −2 dBFS sine wave input, 40 MSPS output data rate, and PLL disabled (Table 2, AC Specifications). This value is guaranteed over the full industrial temperature range and reflects the device's optimized noise floor for mid-band cellular signal digitization.
