Introduction

The AD9257BCPZ-40 is an 8-channel, 14-bit, 40MSPS analog-to-digital converter (ADC) with built-in on-chip sample-and-hold circuitry designed specifically for low cost, low power, small size, and ease of use. The ADC's outstanding dynamic performance and low power consumption make it suitable for applications requiring small packages. The AD9257BCPZ-40 uses a 1.8V single power supply and LVPECL/CMOS/LVDS compatible sample rate clock signal to maximize its operating performance. Many applications are met without the need for an external voltage reference source or driver.

The AD9257BCPZ-40 automatically multiplies the sample rate clock to produce the appropriate LVDS serial data rate. It provides a data clock output (DCO) for capturing data at the output, and a frame clock output (FCO) for sending new output byte signals. It also supports independent closure of channels; Typical power consumption is less than 2 mW when all channels are disabled.

In addition, the AD9257BCPZ-40 also has a variety of built-in features to fully improve device flexibility and minimize system costs, such as programmable clock and data alignment, generation of programmable digital test codes. Available digital test codes include built-in fixed codes and pseudo-random codes, as well as user-defined test codes entered through the serial port interface (SPI).

The AD9257BCPZ-40 comes in a RoHS-compliant 64-pin LFCSP package. The rated temperature range is −40°C to +85°C industrial temperature range.
