Introduction

AI Translation

The AD7671 is a 16-bit, 1MSPS, charge redistribution SAR ADC operating from a 5V single supply. It integrates a high-speed 16-bit sampling ADC, a resistor scaler for input range adjustment, an internal conversion clock, error correction circuitry, and both serial and parallel system interfaces. The AD7671 is factory hardware-calibrated and comprehensively tested to ensure compliance with AC parameters such as SNR and THD, in addition to standard DC parameters (gain, offset, and linearity). It offers three sampling modes: an ultra-high throughput mode (Warp mode); a fast mode (Normal mode) for asynchronous conversion rate applications; and a low-power mode (Pulse mode) for power-sensitive applications, where power consumption scales proportionally with throughput. The AD7671 is a fast, low-power, single-supply, precision 16-bit ADC offering multiple operating modes to optimize performance for specific applications. In Warp mode, the AD7671 can convert 1,000,000 samples per second (1MSPS). The AD7671 provides on-chip sample-and-hold and successive approximation ADC with no pipeline delay, making it ideal for multiplexed multi-channel applications. It supports both bipolar and unipolar input ranges, selectable by changing the connections of the input resistor scaler. The AD7671 operates from a 5V single supply and is compatible with 5V or 3V digital logic interfaces. Available in a 48-lead LQFP or 48-lead LFCSP package, it offers a space-saving, flexible configuration with serial or parallel interface options. The AD7671 is a pin-compatible upgrade to the AD7665 and AD7664.
