May 8, 2014 – Analog Devices ( www.analog.com , NASDAQ: ADI), a global leader in high-performance semiconductors for signal processing applications, is launching two 16-bit 1MSPS A/D converters featuring pseudo-differential and differential input options, respectively. Both the AD7902 Dual Pseudo-Differential and AD7903 Dual Differential converters are 16-bit 1MSPS PulSAR® A/D converters that enable simultaneous and independent signal chains, providing two sampling solutions in a single package. The newly released A/D converters consume 12mW of power at 1MSPS each, which is 70% lower than competing products. Power consumption depends on the throughput rate, which addresses heat dissipation issues inherent in the design characteristics of high-density data acquisition systems. These two types of A/D converters feature a maximum of +/-0.5 LSB and 94 dB SNR for excellent accuracy and precision, making them suitable for a wide range of industrial and instrumentation applications.

Both types of A/D converters are equipped with a multi-purpose serial interface port and are implemented as physically isolated devices, enabling the design of a robust signal chain while considering functional safety. In addition, physical isolation allows for verification and backup measurements, which is useful for detecting end-system faults.

These two types of A/D converters can also be designed as part of a circuit for data acquisition applications using ADI’s ADA4841-1, ADA4941-1, ADA4940 low-noise, low-distortion, rail-to-rail output amplifiers, ADP7104 low-noise LDO, and ADR4525 voltage reference series.
