Product details
Overview
AD9265BCPZ-80 from Analog Devices is a 16-bit, 80 MSPS analog-to-digital converter optimized for IF sampling in communications receivers. It operates from a single 1.8 V analog supply, delivers 79.7 dBFS SNR at 70 MHz input, supports differential analog inputs up to 650 MHz bandwidth, and features on-chip dither and programmable voltage reference for flexible system integration in LTE and W-CDMA baseband processing.
For engineers reviewing the AD9265BCPZ-80 datasheet, AD9265BCPZ-80 pinout, AD9265BCPZ-80 application, or AD9265BCPZ-80 equivalent, this page provides verified technical context, validated pin functions, confirmed AC/DC specifications at 80 MSPS, real-world use cases in multimode digital receivers, and two documented alternative ADCs with explicit functional and application-level differences.
Technical Context
The AD9265BCPZ-80 implements a multistage differential pipelined ADC architecture with integrated error correction logic, guaranteeing no missing codes across −40°C to +85°C. Its analog front end includes a wide-bandwidth track-and-hold amplifier supporting 1 Vp-p to 2 Vp-p input ranges and 650 MHz small-signal bandwidth.
Digital interface flexibility is provided via selectable 1.8 V CMOS or LVDS (DDR) outputs, with a dedicated data clock output (DCO) and serial port control (SPI) for configuration of dither, clock duty cycle stabilization, power-down modes, and output formatting (offset binary, twos complement, gray code).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - guarantees full-scale linearity and no missing codes over industrial temperature range. |
| Max Sampling Rate | 80 MSPS - fixed maximum conversion rate for AD9265BCPZ-80 variant, enabling Nyquist-limited IF sampling up to 40 MHz. |
| SNR @ 70 MHz | 79.7 dBFS - measured at 25°C with −1.0 dBFS input, defining usable dynamic range for high-fidelity signal capture. |
| SFDR @ 70 MHz | 94 dBc - worst-case spurious-free dynamic range without dither, critical for adjacent-channel rejection in cellular receivers. |
| Analog Input Bandwidth | 650 MHz - enables direct RF/IF sampling of signals up to third Nyquist zone without external filtering degradation. |
| Power Consumption | 254 mW (CMOS) / 308 mW (LVDS) at 80 MSPS - low-power operation suitable for dense, thermally constrained baseband modules. |
| Supply Voltages | AVDD = 1.8 V, DRVDD = 1.8 V, SVDD = 1.8 V - single-supply analog core with independent digital output driver rail for interface compatibility. |
Pinout & Package
AD9265BCPZ-80 is housed in a Pb-free, 48-lead LFCSP (CP-48-9) package with exposed thermal pad requiring solder connection to AGND for proper analog performance and thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN+, VIN− | Differential analog input | Accepts balanced RF/IF signals up to 650 MHz; common-mode bias set by internal VCM output (0.9 V). |
| CLK+, CLK− | Differential clock input | Accepts CMOS/LVDS/LVPECL clocks; internal duty cycle stabilizer compensates for input skew up to ±25%. |
| D0–D15 | Parallel digital output | 16-bit DDR data bus; configurable as 1.8 V CMOS or LVDS (interleaved pairs), with DCO for synchronous latching. |

| CSB, SCLK/DFS, SDIO/DCS | SPI interface | 3-wire serial port for register configuration including reference mode, output format, and BIST activation. |
| VREF, SENSE, RBIAS | Reference subsystem | Supports internal 1.0 V reference (±12 mV error) or external reference; SENSE selects mode; RBIAS sets bias current. |
Key Features
| Feature | Design Value |
|---|---|

| Differential analog input | Maintains 79.7 dBFS SNR up to 70 MHz input frequency, enabling high-fidelity digitization in GSM/EDGE/W-CDMA front ends. |
| Integer 1-to-8 clock divider | Allows use of higher-frequency, lower-jitter master clocks while maintaining precise 80 MSPS sampling timing. |
| Built-in self-test (BIST) | Verifies ADC functionality without external stimulus-critical for field-deployed telecom equipment diagnostics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9265BCPZ-105 | Higher max sampling rate (105 MSPS); identical 16-bit resolution, SNR (79.2 dBFS), and package; 15% higher power (341 mW CMOS). | Required for wider IF bandwidths (>40 MHz) or higher oversampling ratios in LTE-A carrier aggregation. | Select AD9265BCPZ-105 only when system clock architecture supports ≥105 MSPS sustained throughput and thermal budget allows +87 mW. |
| AD9255BCPZ-80 | 14-bit resolution, same 80 MSPS rate, pin-compatible LFCSP-48 package, 76.5 dBFS SNR at 70 MHz, lower power (194 mW). | Suitable for cost-sensitive, lower-dynamic-range applications like narrowband IoT gateways where 16-bit precision is unnecessary. | Choose AD9255BCPZ-80 for migration paths where board layout reuse is mandatory but ENOB ≤12.5 bits suffices for target modulation schemes. |
Compared with AD9265BCPZ-105, the AD9265BCPZ-80 trades 25 MSPS headroom for 87 mW power reduction and relaxed clock jitter requirements; versus AD9255BCPZ-80, it delivers +3.2 dB SNR and +1 LSB resolution at the cost of +60 mW and stricter analog layout constraints.

FAQ
What is the maximum analog input frequency supported by the AD9265BCPZ-80?
The AD9265BCPZ-80 supports analog input frequencies up to 300 MHz for IF sampling applications, with a specified small-signal analog input bandwidth of 650 MHz. At 70 MHz input, it achieves 79.7 dBFS SNR and 94 dBc SFDR, confirming effective operation well into the second Nyquist zone. Performance degrades gradually beyond 140 MHz, with SNR dropping to 77.5 dBFS at 200 MHz per datasheet Table 2.
Does the AD9265BCPZ-80 support both CMOS and LVDS digital outputs?
Yes, the AD9265BCPZ-80 supports both 1.8 V CMOS and LVDS (DDR) digital outputs, selected via hardware pins LVDS and LVDS_RS or through SPI register configuration. In LVDS mode, outputs are interleaved (e.g., D0/1+, D0/1−), while CMOS mode provides standard parallel D0–D15. Power consumption differs: 254 mW (CMOS) vs. 308 mW (LVDS) at 80 MSPS.
What is the purpose of the SYNC pin on the AD9265BCPZ-80?
The SYNC pin on the AD9265BCPZ-80 provides hardware synchronization across multiple ADCs in time-aligned sampling systems. When asserted, it resets the internal pipeline and aligns sampling edges across devices. Timing requires setup (0.3 ns) and hold (0.4 ns) relative to the rising edge of CLK+, as defined in Table 5 of the datasheet. It is used exclusively in slave mode configurations.
How does the on-chip dither function improve performance of the AD9265BCPZ-80?
The on-chip dither in the AD9265BCPZ-80 injects controlled noise to randomize quantization distortion, improving SFDR by up to 13 dB at low-input-power conditions (e.g., −23 dBFS). At 70 MHz, SFDR increases from 94 dBc (no dither) to 110 dBc with dither enabled-critical for detecting weak interferers in crowded spectrum environments like cellular base stations.
What is the thermal pad requirement for the AD9265BCPZ-80 LFCSP package?
The exposed thermal pad on the bottom of the AD9265BCPZ-80's 48-lead LFCSP package must be soldered directly to the PCB ground plane. This connection serves as the analog ground reference for the input stage and is essential for achieving specified SNR, thermal resistance (θJA = 24.5°C/W), and reliability. Failure to connect the pad results in degraded noise performance and potential thermal runaway under full-load operation.
