TI Introduces 16-bit, 2MSPS SAR ADC with Serial LVDS Interface

Aug 4, 2006

DALLAS (August 4, 2006) – Texas Instruments Incorporated (TI) (NYSE: TXN) today announced the industry's first 16-bit, 2MSPS SAR analog-to-digital converter (ADC) family to offer a serial LVDS interface. The ADS8413 and ADS8410 utilize serial LVDS outputs to provide data transfer of up to 200Mbps with reduced digital noise. The devices are well-suited for high-speed, high-precision applications such as medical instrumentation, communications, data acquisition and closed-loop systems. (See www.ti.com/sc06143.) 

The ADS8413 has a pseudo-bipolar, differential input and features excellent AC performance without compromising DC precision: -107dB total harmonic distortion (THD), 92dB signal-to-noise ratio (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 is designed to support daisy chaining or cascading of multiple devices on the same bus. Both devices feature low 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 (5uW).
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.

Availability and Packaging

The ADS8413 and ADS8410 are available now in 48-pin QFN packages from TI and its authorized distributors. The ADS8413 is priced at $24.05 in 1,000-piece quantities; the ADS8410 is priced at $23.00 in 1,000-piece quantities (suggested resale pricing). Evaluation modules (EVMs) are also available.

TI offers analog engineers a wide-ranging support infrastructure that includes training and seminars, design tools and utilities, technical documentation, evaluation modules, an online KnowledgeBase, a product information hotline and a comprehensive offering of samples that ship within 24 hours of request.
