The ADS8413 and ADS8410 from Texas Instruments (TI) are 16-bit, 2 Msps successive-approximation register (SAR) analog-to-digital converters (ADC) that offer a serial LVDS interface. These devices use serial LVDS outputs to provide data transfer of up to 200 Mbps with reduced digital noise. The devices are well-suited for high-speed, high-precision applications.

The ADS8413 has a pseudo-bipolar, differential input and features excellent ac performance without compromising dc precision: -107 dB total harmonic distortion (THD), 92 dB signal-to-noise ratio (SNR) and +/-1 LSB integral nonlinearity (INL). The ADS8410 has a unipolar, single-ended input and features –98 dB THD, 87.5 dB SNR and +/-1 LSB INL.

The LVDS interface is designed to support daisy chaining or cascading of multiple devices on the same bus. Both devices feature low power dissipation of 290 mW at 2 Msps 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 (with 5-μW power consumption).

TI provides customers with an advanced signal chain solution for high-speed, high-precision applications including wideband amplifiers, such as the THS4031, to drive the analog inputs of the ADC, and deserializers, such as the SN65LVDS152, to convert serial LVDS into parallel data.

The ADS8413 and ADS8410 are available now in 48-pin QFN packages. The ADS8413 is priced at $24.05 in 1000-piece quantities, and the ADS8410 is priced at $23.00, also in 1000-piece quantities.
