ADS6145IRHBT

The ADS6145IRHBT is a 14-bit, 125 MSPS pipelined analog-to-digital converter (ADC) manufactured by Texas Instruments. It accepts a differential input with a 2 Vpp peak-to-peak range and has an analog input bandwidth of 500 MHz. The device operates from a 3.3 V analog supply and a 1.8 V to 3.3 V digital supply, with typical power consumption of 417 mW. Its dynamic performance includes a 73.9 dB signal-to-noise ratio (SNR), 90 dB spurious-free dynamic range (SFDR), and 11.7 effective number of bits (ENOB).

The ADC supports multiple data interfaces including DDR LVDS and parallel CMOS, and offers programmable output clock position and drive strength to simplify data capture. It features an internal reference with support for an external reference, a clock duty cycle stabilizer, and accepts sine, LVCMOS, LVPECL, or LVDS clock inputs with amplitudes down to 400 mV peak-to-peak. The device is designed for applications such as wireless communications infrastructure, software defined radio, power amplifier linearization, test and measurement instrumentation, high-definition video, medical imaging, and radar systems.

The ADS6145IRHBT is available in a surface-mount 32-VFQFN exposed pad package, also designated as 32-VQFN (5x5 mm). It is specified for operation over the industrial temperature range of -40°C to 85°C. The pipelined architecture and high sample rate make it suitable for high-speed signal acquisition and IF sampling applications.
