The AD7671 is a 16-bit, 1 MSPS, charge redistribution SAR, analog-to-digital converter that operates from a single 5 V power supply. It contains a high speed 16-bit sampling ADC, a resistor input scaler that allows various input ranges, an internal conversion clock, error correction circuits, and both serial and parallel system interface ports.

The AD7671 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 (Warp), a fast mode (Normal) for asynchronous conversion rate applications, and, for low power applications, a reduced power mode (Impulse) where the power is scaled with the throughput.

It is fabricated using Analog Devices’ high performance, 0.6 micron CMOS process and is available in a 48-lead LQFP and a tiny 48-lead LFCSP, with operation specified from –40°C to +85°C.

PRODUCT HIGHLIGHTS

Fast Throughput
The AD7671 is a very high speed (1 MSPS in Warp Mode and 800 kSPS in Normal Mode), charge redistribution, 16-bit SAR ADC.
Single-Supply Operation
The AD7671 operates from a single 5 V supply, dissipates only 112 mW typical, even lower when a reduced throughput is used with the reduced power mode (Impulse) and a power-down mode.
Superior INL
The AD7671 has a maximum integral nonlinearity of 2.5 LSB with no missing 16-bit code.
Serial or Parallel Interface
Versatile parallel (8 bits or 16 bits) or 2-wire serial interface arrangement compatible with both 3 V or 5 V logic.
