AD9681 Datasheet 1.8 V Analog-to-digital Converter

Manufacturer: Analog Devices

Overview: Data Sheet Octal, 14-Bit, 125 MSPS, Serial LVDS, 1.8 V Analog-to-Digital Converter.

General Description

The AD9681 is an octal, 14-bit, 125 MSPS analog-to-digital converter (ADC) with an on-chip sample-and-hold circuit that is designed for low cost, low power, small size, and ease of use.

The device 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-patible sample rate clock for full performance operation.

Key Features

  • Low power 8 ADC channels integrated into 1 package 110 mW per channel at 125 MSPS with scalable power options SNR: 74 dBFS (to Nyquist); SFDR: 90 dBc (to Nyquist) DNL: ±0.8 LSB (typical); INL: ±1.2 LSB (typical) Crosstalk, worst adjacent channel, 70 MHz,.
  • 1 dBFS:.
  • 83 dB typical Serial LVDS (ANSI-644, default) Low power, reduced signal option (similar to IEEE 1596.3) Data and frame clock outputs 650 MHz full power analog bandwidth 2 V p-p input voltage range 1.8 V supply operation.
