Texas Instruments Inc. has unveiled a 16bit, 2MSps SAR ADC family, said to be the industry's first to offer a serial LVDS interface. The ADS8413 and ADS8410 use serial LVDS outputs to provide data transfer of up to 200Mbps with reduced digital noise. The devices are suited for high-speed, high-precision applications such as medical instrumentation, communications, DAQ and closed-loop systems.

The ADS8413 has a pseudo-bipolar differential input and promises efficient AC performance without compromising DC precision: -107dB total harmonic distortion (THD), 92dB SNR and 1LSB integral nonlinearity (INL). The ADS8410 has a unipolar, single-ended input and features -98dB THD, 87.5dB SNR and 1LSB INL.

The LVDS interface supports daisy chaining or cascading of multiple devices on the same bus. Both devices feature a power dissipation of 290mW at 2MSps and offer two additional power-saving modes. When used at lower throughput rates, the nap mode enables substantial power-saving options. When not in use, a hardware power-down mode helps conserve energy (5W).

TI provides customers with an advanced signal chain solution for high-speed, high-precision applications including wideband amplifiers to drive the analog inputs of the ADC and deserializers to convert serial LVDS into parallel data.

The ADS8413 and ADS8410 are available in 48-pin QFN packages. The ADS8413 is priced at $24.05 in 1,000-piece quantities. The ADS8410 is priced at $23 in 1,000-piece quantities. Evaluation modules are also available.
