Features and Benefits
The AD7880 is a high speed, low power, 12-bit A/D converter which operates from a single +5 V supply. It consists of a 3 µs track/hold amplifier, a 12 µs successive-approximation ADC, versatile interface logic and a multiple-input range circuit. The part also includes a power save feature.
An internal resistor network allows the part to accept both unipolar and bipolar input signals while operating from a single +5 V supply. Fast bus access to modern microprocessors and digital signal processors.
The AD7880 features a total throughput time of 15 µs and can convert full power signals up to 33 kHz with a sampling frequency of 66 kHz.
In addition to the traditional dc accuracy specifications such as linearity, full scale and offset errors, the AD7880 is also fully specified for dynamic performance parameters including harmonic distortion and signal-to-noise ratio.
The AD7880 is fabricated in Analog Devices' Linear Compatible CMOS (LC2MOS) process, a mixed technology process that combines precision bipolar circuits with low power CMOS logic. The part is available in a 24-pin, 0.3 inch wide, plastic or hermetic dual-in-line package (DIP) as well as a small 24-lead SOIC package.
