Texas Instruments has introduced two 14- and 12-bit, 210-MSPS analog-to-digital converters (ADCs) to its pin-compatible, high-speed ADS5546 family. The ADS5547 and ADS5527 provide the highest performance at 210 MSPS with up to 73.3-dBFS signal-to-noise ratio (SNR) and 85-dBc spurious-free dynamic range (SFDR) at 70 MHz input frequency .

This high performance brings benefits such as better range and resolution for radar and imaging, more accurate power amplifier characterization in digital pre-distortion solutions and higher quality for video and imaging systems.

The ADS5547 is the fastest 14-bit ADC available while the ADS5527 provides the same speed for customers requiring only 12-bit resolution, both in a small 7-mm x 7-mm leadless package. The addition of the ADS5547 and ADS5527 at this speed, resolution and small size provides designers greater flexibility in component selection.

Customers can achieve maximum performance by combining the ADS5547 and ADS5527 with a TI high-speed amplifier (such as THS4509 or THS9001), wideband digital down-converter/up-converter (GC5016/8) and clock synchronizer and jitter cleaner (CDCM7005).

Both the ADS5547 and ADS5527 are available now in 48-pin quad flat no-lead (QFN) packages. The ADS5547 is priced at $82.50 each and the ADS5527 is priced at $45.00 each in 1,000-piece quantities.
