Texas Instruments has introduced a 14 bit, 62 MSPS CMOS range analogue-to-digital converter from the company's Burr-Brown product range targeting wireless communications, imaging and instrumentation applications.

The device's CMOS process design allows T1 to offer a high-performance 14 bit data converter with higher sampling and lower power consumption.

The signal-to-noise ratio performance of 72 dB, spurious-free dynamic range of 85 dB and 1.2 W power consumption makes this device suitable for a variety of existing and emerging high-end systems.

Specific applications include base station receivers, digital radio, professional studio cameras, magnetic resonance imaging, spectrum analysers and optical performance monitoring.

The ADS5422 operates on a single +5 V analogue supply and features a high-bandwidth linear track-and-hold, an internal/external reference option, flexible input range and a low DNL of ±0.5 LSB.

The clock input can accept a low-level differential sine server or square wave signal down to 0.5 Vp-p, further improving the SNR performance.
