AD7654:  Dual, 2-Channel, Simultaneous Sampling, PulSAR®, 500 kSPS, 16-Bit ADC

Product Description

The AD7654 is a low cost, dual, 16-bit, charge redistribution SAR, Analog-to-Digital Converter which operates from a single 5 V power supply. It contains two low noise, wide bandwidth track/hold amplifiers which allow simultaneous sampling, a high-speed 16-Bit sampling ADC, an internal conversion clock, error correction circuits, and both serial and parallel system interface ports.

The AD7654 is hardware factory calibrated and is comprehensively tested to ensure such ac parameters as signal-to-noise ratio (SNR) and total harmonic distortion (THD), in addition to the more traditional dc parameters of gain, offset, and linearity.

It features a very high sampling rate mode (Normal) and, for low power applications, a reduced power mode (Impulse) where the power is scaled with the throughput. It is available in a 48-lead LQFP or a 48-lead LFCSP with operation specified from –40°C to +85°C.
