Convertors claim top performance at 210Msample/s

Texas Instruments has added two 14 and 12bit, 210Msample/s analogue-to-digital convertors (ADCs) to its pin-compatible, high-speed ADS5546 family.

Texas Instruments has added two 14 and 12bit, 210Msample/s analogue-to-digital convertors (ADCs) to its pin-compatible, high-speed ADS5546 family.

The ADS5547 and ADS5527 provide the highest performance at 210Msample/s with up to 73.3dB full-scale signal-to-noise ratio (SNR) and 85dBc spurious-free dynamic range (SFDR) at 70MHz input frequency.

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

The ADS5547 is the fastest 14bit ADC available, and the ADS5527 provides the same speed for customers requiring only 12bit resolution, both in small 7 x 7mm leadless packages.

The addition of the ADS5547 and ADS5527 at this speed, resolution and small sise 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-convertor/up-convertor (GC5016/8) and clock synchroniser 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 US $82.50 each and the ADS5527 is priced at $45.00 each in 1000-piece quantities.
