Product details
Overview
AD9253BCPZRL7-105 from Analog Devices is a quad-channel, 14-bit, 105 MSPS serial LVDS analog-to-digital converter optimized for high-speed imaging and medical ultrasound systems. It operates from a single 1.8 V supply, delivers 74 dB SNR and 90 dBc SFDR at Nyquist, and features 650 MHz full-power analog bandwidth with 2 V p-p differential input range.
For engineers reviewing the AD9253BCPZRL7-105 datasheet, AD9253BCPZRL7-105 pinout, AD9253BCPZRL7-105 application, or AD9253BCPZRL7-105 equivalent, this page provides verified technical context, validated pin functions, confirmed AC/DC specifications, real-world use scenarios, and two rigorously cross-checked alternative parts for quadrature radio receiver and test equipment designs.
Technical Context
The AD9253BCPZRL7-105 implements a multistage pipelined ADC architecture with digital error correction logic, enabling 14-bit resolution at 105 MSPS while maintaining ±0.75 LSB DNL and ±2.0 LSB INL. Its on-chip sample-and-hold circuit supports differential inputs up to 650 MHz, and internal clock multiplication generates LVDS serial data aligned to programmable DCO and FCO outputs.
It integrates four independent ADC channels sharing one 1.8 V AVDD rail and separate 1.8 V DRVDD for LVDS output drivers, with per-channel power-down consuming <2 mW. Serial port interface (SPI) configures output resolution (12/14/16-bit), bit orientation, test patterns, and clock divider settings - all validated in Rev. E datasheet Tables 1–5 and Figure 20–29.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel, 14-bit, high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9253BCPZRL7-125 | Higher 125 MSPS sampling rate; 457 mW power at 105 MSPS (vs. 405 mW for -105); identical pinout and SPI register map. | Required for >52.5 MHz IF bandwidth or oversampling applications; not drop-in due to higher thermal load. | Select -125 only if design requires ≥125 MSPS or improved SNR at lower input frequencies (75.2 dBFS @ 9.7 MHz). |
| AD9633BCPZRL7-105 | 12-bit resolution, same 48-lead LFCSP package and pin-compatible layout; 85 mW/channel at 105 MSPS; 70 dB SNR. | Suitable for cost-sensitive, lower-dynamic-range applications like basic spectrum analyzers where 14-bit precision is unnecessary. | Choose -105 variant of AD9633 only when 12-bit ENOB (≈11.5 bits) suffices and board space reuse is critical. |
Compared with AD9253BCPZRL7-105, the -125 variant trades higher power for extended Nyquist bandwidth, while AD9633BCPZRL7-105 sacrifices 2 bits of resolution and 4 dB SNR to halve power per channel - making each choice a deliberate trade-off between fidelity, speed, and thermal budget.

FAQ
What is the maximum analog input frequency supported by the AD9253BCPZRL7-105?
The AD9253BCPZRL7-105 supports a full-power analog bandwidth of 650 MHz, meaning it maintains specified SNR/SFDR performance for input signals up to that frequency. At 70 MHz input, it achieves 74.4 dB SNR and 89 dBc SFDR per Rev. E datasheet Table 2; performance degrades gradually beyond 140 MHz but remains functional up to 200 MHz with 70.7 dB SNR.
Does the AD9253BCPZRL7-105 require an external voltage reference?
No, the AD9253BCPZRL7-105 includes an internal 1.0 V reference with ±2% tolerance over temperature, specified in Table 1. It can operate with VREF pin left unconnected or configured for external reference via SENSE pin control - but default operation uses the internal reference, eliminating external component count.
How is channel synchronization achieved across the four ADCs in the AD9253BCPZRL7-105?
The AD9253BCPZRL7-105 uses a shared differential clock (CLK+/CLK−) and dedicated SYNC input to align internal clock dividers across all four channels. When SYNC is asserted, all channels reset their frame boundaries simultaneously, ensuring deterministic inter-channel phase alignment - critical for beamforming and I/Q demodulation.
What LVDS output standards does the AD9253BCPZRL7-105 support?
The AD9253BCPZRL7-105 supports two LVDS output modes: ANSI-644 compliant (345 mV typical differential output voltage) and low-power reduced-swing mode (200 mV typical), selectable via SPI register. Both modes maintain 1.25 V common-mode output voltage and are compatible with standard LVDS receivers.
Can the AD9253BCPZRL7-105 operate with a single 1.8 V supply for both analog and digital sections?
Yes - the AD9253BCPZRL7-105 uses separate 1.8 V supplies: AVDD powers analog circuitry (pins 3,4,7,34,39,45,46), and DRVDD powers LVDS output drivers (pins 8,29). While both are 1.8 V, they must be independently decoupled; mixing them risks increased digital switching noise coupling into analog sampling paths.
