TI – Highest-performance and smallest 12-bit / 500MSPS ADC

A new monolithic 12-bit, 500 MSPS (mega samples per second) analog-to-digital converter (ADC) has been unveiled by Texas Instruments Incorporated (TI). The device provides ‘unmatched’ size and performance, says the company.

The pipeline ADC offers 64.5dBFS signal-to-noise ratio (SNR) up to 500MHz input frequency at 500MSPS, bringing a new class of performance to users previously confined to 8- and 10-bits of resolution. In a space-saving 14mm x 14mm package, the new ADC meets the resolution and speed requirements of applications such as communications, amplifier linearization, test and measurement instrumentation, software-defined radio and radar and imaging systems.

Manufactured in TI’s proprietary BiCom3 process technology optimized for high speed and low noise, the ADS5463 provides 84dBc SFDR, 10.5 ENOB and an iinput bandwidth of 2GHz while only consuming 2.25W of power. The ADC includes an internal reference generator and LVDS outputs with a half-clock rate, data-ready signal to simplify designs. In addition, the ADS5463 is a pin-compatible family member to TI’s 13-bit, 250/210 MSPS ADS5444/ADS5440 and provides a wide range of increased benefits to the system.

TI provides customers a state-of-the-art signal chain to complement the ADS5463 including high-speed amplifiers (THS4304, THS4509, THS4511, THS9000/9001), high-speed digital-to-analog converters (DAC5687) and a clock synchronizer and jitter cleaner (CDCM7005). The ADS5463 is also optimized to work with TI’s TMS320T high-performance DSP platforms, says the company.
