AD9645
Overview
The AD9645 is a dual, 14-bit, 80 MSPS/125 MSPS analog-todigital 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.
- 8 V supply operation Low power: 122 mW per channel at 125 MSPS with scalable power options SNR = 74 dBFS (to Nyquist) SFDR = 91 dBc at 70 MHz DNL = ±0.65 LSB (typical); INL = ±1.5 LSB (typical) Serial LVDS (ANSI-644, default) and low power, reduced range option (similar to IEEE 1596.3) 650 MHz full power analog bandwidth 2 V p-p input voltage range Serial port control Full chip and individual channel power-down modes Flexible bit orientation Built-in and custom digital test pattern generation Clock divider Programmable output clock and data alignment Programmable output resolution Standby mode
