Texas Instruments High-Performance Analog Analog to Digital Converters (ADC) ADS5103IPFB

The ADS5103IPFB is a 10-bit analog-to-digital converter (ADC) from Quarktwin Technology Ltd. designed for low-power applications. It operates on a single 1.8 V supply and features a maximum sampling rate of 40 MSPS. The device includes a differential input configuration, which enhances common-mode noise rejection, making it suitable for applications such as ultrasound, digital cameras, and baseband digitization. The ADC provides a 10-bit parallel output data bus with 3-state outputs, compatible with both 1.8 V and 3.3 V logic levels. It has a signal-to-noise ratio of 58 dB at 20 MHz and a power dissipation of 105 mW during normal operation, with a low power-down mode consuming only 336 µW. The internal reference can be bypassed for external reference use, allowing flexibility in meeting specific accuracy and temperature drift requirements. The ADS5103IPFB is housed in a 48-TQFP package, making it suitable for compact designs.
