The AD7665 is a 16-bit, 570 kSPS, 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 scalar, which allows various input ranges, an internal conversion clock, error correction circuits, and both serial and parallel system interface ports.
The AD7665 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) and, for asynchronous conversion rate applications, a fast mode (Nor-mal) 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 with operation specified from -40°C to +85°C.
PRODUCT HIGHLIGHTS
- Fast Throughput
The AD7665 is a very high speed (570 kSPS in Warp Mode and 500 kSPS in Normal Mode), charge redistribution, 16-bit SAR ADC. - Single-Supply Operation
The AD7665 operates from a single 5 V supply, dissipates only 64 mW typical, even lower when a reduced throughput is used with the reduced power mode (Impulse) and a power-down mode. - Superior INL
The AD7665 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.
