Quad-Channel, 14-bit, 250-MSPS Low-Power ADC - ADS4449

ADS4449 (ACTIVE)

Quad-Channel, 14-bit, 250-MSPS Low-Power ADC

Recommended alternative parts

  • ADS58H40  - The device has SIMILAR FUNCTIONALITY but is not functionally equivalent to the compared device.   Wideband Feedback and Receiver IF, same pinout as ADS4449
  • ADS42B49  - The device has SIMILAR FUNCTIONALITY but is not functionally equivalent to the compared device.   Dual 14-bit 250MSPS ADC with buffered inputs

Description

The ADS4449 is a high-linearity, quad-channel, 14-bit, 250-MSPS, analog-to-digital converter (ADC). The four ADC channels are separated into two blocks with two ADCs each. Designed for low power consumption and high spurious-free dynamic range (SFDR), the device has low-noise performance and outstanding SFDR over a large input frequency range.
