ADC14X250RHBR

The ADC14X250RHBR is a monolithic single-channel high-performance analog-to-digital converter from Texas Instruments. It converts analog input signals into 14-bit digital words at a sampling rate of 250 MSPS. The device uses a differential pipelined architecture with an integrated input buffer to provide excellent dynamic performance and low power consumption.

Key specifications include a resolution of 14 bits, sampling rate of 250 MSPS, signal-to-noise ratio (SNR) of 70.1 dBFS at 240 MHz input, spurious-free dynamic range (SFDR) of 87 dBFS, and typical power dissipation of 584 mW. The digital output interface is JESD204B Subclass 1 with a single lane serial data rate up to 5 Gb/s.

The ADC features buffered analog inputs with differential input phase and amplitude correction, an input sampling clock divider (divide-by-1, 2, 4, 8), and a 4-wire serial peripheral interface (SPI) for configuration. It is rated for operation over the -40°C to 85°C temperature range, with performance rated up to 105°C at the thermal pad.

The device is offered in a surface-mount 32-pin VQFN package (5x5 mm, 0.5 mm pitch). It is supplied in tape and reel packaging with 3000 pieces per reel. The ADC14X250RHBR is RoHS and REACH compliant, with a moisture sensitivity level (MSL) of Level 3.
