ADC34J44IRGZR

The Texas Instruments ADC34J44IRGZR is a quad-channel, 14-bit, 125-MSPS analog-to-digital converter (ADC) designed for high-linearity and ultra-low power consumption. It operates from a single 1.8-V supply and supports a JESD204B serial interface to reduce pin count and enable high system integration density. The device features a pipelined architecture with differential inputs and simultaneous sampling capability.

Key performance metrics include a typical SNR of 72 dBFS and SFDR of 86 dBc at 70 MHz input frequency, with channel isolation of 105 dB. Power consumption is 203 mW per channel at 160 MSPS. The ADC includes an internal dither option and a flexible input clock divider (divide-by-1, -2, -4) for system clock architecture flexibility. It supports JESD204B Subclass 0, 1, and 2, as well as multi-chip synchronization.

The ADC34J44IRGZR is packaged in a 48-VFQFN Exposed Pad (7x7 mm) surface-mount package and operates over the industrial temperature range of -40°C to +85°C. It is RoHS3 compliant and has a Moisture Sensitivity Level of Level-3 (260°C, 168 hours). The package is supplied in tape and reel with 2500 pieces per reel, suitable for high-volume assembly.
