Description
- Product Details
- The AD9655 is a dual, 16-bit, 125 MSPS analog-to-digital converter (ADC) with an on-chip sample-and-hold circuit designed for low cost, low power, small size, and ease of use. The product operates at a conversion rate of up to 125 MSPS and is optimized for outstanding dynamic performance and low power in applications where a small package size is critical.
- The ADC requires a single 1.8 V power supply and an LVPECL-/ CMOS-/LVDS-compatible sample rate clock for full performance operation. External reference or driver components are not required for many applications.
- The ADC automatically multiplies the sample rate clock for the appropriate LVDS serial data rate. A data clock output (DCO) for capturing data on the output and a frame clock output (FCO) for signaling a new output byte are provided. Individual channel power-down is supported.
- The AD9655 typically consumes less than 2 mW in SPI powerdown mode. The available digital test patterns include built-in deterministic and pseudorandom patterns, along with custom user-defined test patterns entered via the serial port interface (SPI).
- The AD9655 is available in a RoHS-compliant, 32-lead LFCSP. It is specified over the industrial temperature range of −40°C to +85°C. This device is protected by a U.S. patent.
- Product Highlights
- 1. Small Footprint. Two ADCs are contained in a small, spacesaving package.
- 2. Pin compatible to the AD9645 14-bit and AD9635 12-bit dual ADCs.
- 3. Ease of use. A DCO operates at frequencies of up to 500 MHz and supports double data rate (DDR) operation.
- 4. User Flexibility. The SPI control offers a wide range of flexible features to meet specific system requirements.
