双通道、14 位、125MSPS 模数转换器 ADC - 增强型产品 64-VQFN -55 to 125
The ADS4245 is a low-speed variant of the ADS42xx ultralow-power family of dual-channel, 14-bit analog-to-digital converters ADCs. Innovative design techniques are used to achieve high-dynamic performance, while consuming extremely low power with 1.8V supply. This topology makes the ADS4245 well-suited for multi-carrier, wide-bandwidth communications applications.
The ADS4245 has gain options that can be used to improve SFDR performance at lower full-scale input ranges. These device includes a dc offset correction loop that can be used to cancel the ADC offset. Both DDR double data rate LVDS and parallel CMOS digital output interfaces are available in a compact VQFN-64 PowerPAD package.
The device includes internal references while the traditional reference pins and associated decoupling capacitors have been eliminated. The ADS4245 is specified over the military temperature range –55°C to 125°C.
