ADS5525IRGZT

The ADS5525IRGZT is a high-performance 12-bit analog-to-digital converter (ADC) from Texas Instruments, designed for high-speed data acquisition applications. It operates at a maximum sampling rate of 170 MSPS and offers a pipelined architecture with an internal sample-and-hold circuit.

Key electrical specifications include a typical SNR of 71.2 dB and SFDR of 87 dBc, with an effective number of bits (ENOB) of 11.5 bits. At a 70 MHz IF, the SNR is 70.5 dBFS and SFDR is 84 dBc, with minimum ENOB of 11 bits. The ADC supports differential input with a 2 V p-p voltage range and provides programmable gain up to 6 dB for trade-offs between SNR and SFDR at high IF frequencies.

The device operates from a 3.0V to 3.6V analog and digital supply, with typical power consumption of 1100 mW. It is housed in a 48-VFQFN exposed pad package (7x7 mm) and supports surface mount mounting. Data output options include double data rate (DDR) LVDS and parallel CMOS interfaces.

Typical applications include wireless communications infrastructure, software defined radio, power amplifier linearization, test and measurement instrumentation, high-definition video, medical imaging, and radar systems.
