Product details
Overview
AD9262BCPZRL7-5 from Analog Devices is a dual-channel, 16-bit continuous-time sigma-delta analog-to-digital converter optimized for quadrature baseband sampling in communications receivers. It delivers 85.3 dB SNR and −87 dBc SFDR at 1.2 MHz input with 5 MHz analog bandwidth, operates on 1.8 V analog supply, consumes 600 mW, and supports 30–160 MSPS output data rates. It is used in W-CDMA and LTE direct-conversion receiver front ends.
For engineers reviewing the AD9262BCPZRL7-5 datasheet, AD9262BCPZRL7-5 pinout, AD9262BCPZRL7-5 application, or AD9262BCPZRL7-5 equivalent, key selection considerations include its 5 MHz real-bandwidth variant, integrated dc/quadrature correction, 64-lead LFCSP package, and support for interleaved 16-bit CMOS outputs with DCO timing.
Technical Context
The AD9262BCPZRL7-5 implements a fifth-order continuous-time Σ-Δ modulator with 32× oversampling (640 MSPS internal clock), enabling high alias rejection without external antialiasing filters. Its passive 1 kΩ differential input impedance relaxes driver amplifier requirements.
It integrates decimation filters with programmable pass-band transition (6.5 MHz), sample rate conversion, on-chip PLL clock multiplier, voltage reference, and digital correction blocks for inter-channel gain/phase mismatch-critical for complex I/Q signal chains in zero-IF architectures.

| Output Data Rate | 30–160 MSPS - user-selectable via decimation ratio; supports flexible interface timing to FPGA or ASIC logic. |
| Input Impedance | 1 kΩ differential - resistive, frequency-flat input simplifies anti-aliasing network design and eliminates need for active termination. |
| Supply Voltages | 1.8 V AVDD, 1.8–3.3 V DRVDD - dual-voltage domain enables compatibility with both low-voltage logic and legacy 3.3 V interfaces. |
Pinout & Package
The AD9262BCPZRL7-5 is housed in a 64-lead LFCSP (Lead Frame Chip Scale Package) with exposed thermal pad (EPAD) that must be soldered to PCB ground for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK+, CLK− | Differential clock inputs | Accept CMOS or LVPECL-level clocks; define 640 MSPS modulator sampling; duty cycle tolerance ±10%. |
| VIN+A, VIN−A / VIN+B, VIN−B | Differential analog inputs (Ch A/B) | 1 kΩ resistive, 2 V p-p full-scale differential input; common-mode range 1.7–1.9 V. |
| D0A–D15A, D0B–D15B | Parallel digital outputs | 16-bit CMOS outputs per channel; support offset binary, Gray, or two's complement format; interleavable onto single bus. |
| DCO | Data clock output | Synchronizes output data edges; skew ≤3 ns to D0x–D15x; essential for reliable capture by receiving logic. |
| ORA, ORB | Overrange indicators | Active-high flags signaling analog input saturation per channel; enables real-time clipping detection and AGC response. |
| SDIO, SCLK, CSB | SPI serial interface | 3-wire configuration port for register writes/reads; supports daisy-chaining and dynamic parameter adjustment. |
| RESET | Asynchronous reset | Hard resets internal logic, clears FIFOs, and reinitializes calibration blocks; synchronous release required for stable operation. |
| AVDD, DVDD, DRVDD, CVDD | Power supplies | Separate analog (1.8 V), digital core (1.8 V), output driver (1.8–3.3 V), and clock (1.8 V) rails minimize noise coupling. |
| AGND, DGND, CGND | Ground returns | Partitioned ground planes prevent digital switching noise from corrupting analog conversion accuracy. |
| VREF, CFILT | Reference subsystem | Internal 500 mV reference with external 10 µF decoupling capacitor; CFILT stabilizes reference loop for low-noise operation. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated dc and quadrature correction | Compensates for inter-channel gain/phase mismatch in real time-enables <−110 dB crosstalk and stable I/Q demodulation in zero-IF receivers. |
| On-chip PLL clock multiplier | Generates precise 640 MSPS modulator clock from lower-frequency external source-eliminates need for ultra-high-frequency clock distribution. |
| Selectable 5 MHz real analog bandwidth | Optimized for W-CDMA and multicarrier GSM/EDGE applications-provides best-in-class SNR/SFDR trade-off within this bandwidth tier. |

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 |
|---|---|---|---|
| AD9262BCPZ-5 | Same die, identical specs, non-tape-and-reel packaging; no built-in reel logistics for automated assembly. | Identical functional performance; differs only in packaging format and reel quantity (not applicable to AD9262BCPZRL7-5's 7-inch reel). | Select AD9262BCPZRL7-5 for SMT production requiring standard 7-inch tape-and-reel delivery. |
| AD9262BCPZ | 2.5 MHz bandwidth variant; SNR degrades to 87.9 dB at 600 kHz but improves at lower frequencies; different decimation filter cutoff. | Better suited for narrowband applications like CDMA2000 where 2.5 MHz BW suffices and higher SNR at sub-MHz tones is prioritized. | Choose AD9262BCPZRL7-5 when 5 MHz real bandwidth and guaranteed −87 dBc SFDR at 1.2 MHz are required. |
Compared with AD9262BCPZ-5, AD9262BCPZRL7-5 offers identical electrical performance with factory-optimized tape-and-reel packaging for high-volume SMT lines; versus AD9262BCPZ, it trades lower-frequency SNR for wider 5 MHz bandwidth and superior SFDR at mid-band frequencies critical for multicarrier systems.

FAQ
What is the analog input bandwidth specification for AD9262BCPZRL7-5?
The AD9262BCPZRL7-5 is the 5 MHz bandwidth variant of the AD9262 family. Its analog input bandwidth is specified as 5 MHz, meaning it maintains full dynamic performance-including 85.3 dB SNR and −87 dBc SFDR-up to 5 MHz input frequency. This bandwidth is fixed by internal decimation filter settings and cannot be reconfigured to 2.5 MHz or 10 MHz modes.
Does AD9262BCPZRL7-5 support interleaved output mode?
Yes, AD9262BCPZRL7-5 supports interleaved output mode, allowing Channel A and Channel B 16-bit data to be multiplexed onto a single 16-bit bus. This reduces PCB routing density and simplifies interface to FPGAs with limited I/O resources. Interleaving is controlled via SPI register configuration and requires proper DCO synchronization.
What power supply voltages does AD9262BCPZRL7-5 require?
AD9262BCPZRL7-5 requires four independent supplies: AVDD = 1.8 V (analog core), DVDD = 1.8 V (digital core), DRVDD = 1.8 V to 3.3 V (output driver level), and CVDD = 1.8 V (clock circuitry). Each supply must be independently decoupled; DRVDD voltage selects CMOS output logic level and affects VOL/VOH specifications.
How does the integrated dc and quadrature correction work in AD9262BCPZRL7-5?
AD9262BCPZRL7-5 incorporates dedicated hardware blocks that continuously estimate and correct for inter-channel dc offset, gain mismatch, and phase skew between its two ADC channels. This correction occurs digitally post-decimation and is applied in real time, ensuring <−110 dB crosstalk and enabling high-fidelity I/Q signal reconstruction without external calibration firmware.
Is the exposed thermal pad on AD9262BCPZRL7-5 electrically connected?
Yes, the exposed pad (EPAD, Pin 65) on AD9262BCPZRL7-5 is internally connected to AGND and must be soldered to the PCB ground plane. This connection is mandatory for thermal dissipation (θJC = 1.1°C/W), electrical noise reduction, and mechanical reliability-failure to solder the EPAD violates Absolute Maximum Ratings and risks parametric drift or failure.
