Texas Instruments ADS42B49IRGC25
- Part Number:
- ADS42B49IRGC25
- Manufacturer:
- Texas Instruments
- Ventron No:
- 3014533-ADS42B49IRGC25
- Description:
- IC ADC 14BIT PAR 250MSPS 64VQFN
- Datasheet:
- ADS42B49IRGC25
Description
The ADS42B49 is a dual-channel, 14-bit, 250 MSPS analog-to-digital converter (ADC) with integrated analog input buffers. It utilizes innovative design techniques to achieve high dynamic performance while consuming extremely low power. The presence of analog input buffers makes this device easy to drive and helps achieve high performance over a wide frequency range. The ADS42B49 is well-suited for multi-carrier, wide bandwidth communications applications.
The ADS42B49 has gain options that can be used to improve SFDR performance at lower full-scale input ranges. This device also includes a DC offset correction loop that can be used to cancel the ADC offset. Both DDR LVDS and parallel CMOS digital output interfaces are available in a compact QFN-64 PowerPAD™ package. The device includes internal references while the traditional reference pins and associated decoupling capacitors have been eliminated. The ADS42B49 is specified over the industrial temperature range (-40°C to 85°C).
