AD9253BCPZRL7-105

Overview

The AD9253BCPZRL7-105 is a quad, 14-bit analog-to-digital converter (ADC) from Analog Devices Inc., operating at a maximum conversion rate of 105 MSPS. It features an on-chip sample-and-hold circuit and requires a single 1.8 V power supply. The device provides serial LVDS digital outputs with a data clock output (DCO) and frame clock output (FCO). Key electrical specifications include a signal-to-noise ratio (SNR) of 75.0 dBFS at 30.5 MHz input frequency, a spurious-free dynamic range (SFDR) of 92 dBc, and a full-power analog bandwidth of 650 MHz. Typical differential nonlinearity (DNL) is ±0.75 LSB, and integral nonlinearity (INL) is ±2.0 LSB. The component is housed in a 48-lead LFCSP package and operates within an industrial temperature range of −40°C to +85°C.

Feature Summary

• Quad-channel architecture integrating four independent 14-bit ADCs with on-chip sample-and-hold circuits in a compact footprint.
• Low power consumption of 110 mW per channel at maximum speed, featuring individual channel power-down modes for energy efficiency.
• Flexible digital interface supporting serial LVDS outputs with programmable data alignment, bit orientation, and test pattern generation via SPI.
• Integrated internal voltage reference and common-mode voltage generator, eliminating the need for external driver components in many applications.

Applications

• Medical ultrasound imaging systems
• High-speed data acquisition and imaging equipment
• Quadrature and diversity radio receivers
• Professional test and measurement instruments

Procurement Notes

Verify the specific ordering suffix RL7 confirms tape and reel packaging when sourcing. Confirm that the -105 variant meets the required sampling rate specifications for the target application. Ensure compatibility with the 48-lead LFCSP thermal requirements during system integration.

Selection Notes

Select this model for applications requiring four synchronized channels with 14-bit resolution at speeds up to 105 MSPS. Consider the AD9253-80 or AD9253-125 variants if lower or higher sampling rates are sufficient, as they share pinouts. Evaluate the low-power reduced signal option if LVDS power constraints are critical.

Part Context

The AD9253 belongs to a family of high-performance, low-power quad ADCs designed for space-constrained systems. It offers pin compatibility with the AD9633 12-bit quad ADC, facilitating design upgrades. The device utilizes a pipelined architecture to achieve high throughput while maintaining excellent dynamic performance metrics.

Replacement Considerations

The AD9253BCPZ-105 serves as a direct leaded replacement for the BCPZRL7-105 variant, sharing identical functional specifications and pinout. Other members of the AD9253 family, such as the -80 and -125 versions, are pin-compatible but differ in maximum sampling rates.
