Based on the Pulsar core, the AD7663 is a bipolar 16-bit, 250 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 that allows various input ranges, an internal conversion clock, error correction circuits, and both serial and parallel system interface ports.
The AD7663 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 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.
- Fast Throughput
The AD7663 is a 250 kSPS charge redistribution, 16-bit SAR ADC with various bipolar and unipolar input ranges.
- Single-Supply Operation
The AD7663 operates from a single 5 V supply and dissipates only 35 mW typical. Its power dissipation decreases with the throughput to, for instance, only 15 µW at a 100 SPS throughput. It consumes 7 µW maximum when in power-down.
- Superior INL
The AD7663 has a maximum integral nonlinearity of 3 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.
