Overview: www.DataSheet4U.com ADC3214 High Speed, 14-Bit, 1 MHz, Sampling A/D Converter
With Built-in Sample-and-Hold Amplifier
Introduction
The ADC3214 is a 14-bit, 1 MHz A/D converter with a built-in sampleand-hold amplifier. It was designed for use in applications requiring high speed and high resolution front ends, such as ATE, medical imaging, radar, communications, and analytical instrumentation. The ADC3214 is a cost-effective solution for both time and frequency domain applications. It is capable of digitizing a 500 kHz signal at a 1 MHz rate with a guarantee of no missing codes. Signal-to-noise ratio is 76 dB at input frequencies from DC to 100 kHz. With a 1 MHz sampling rate and a full-scale step response to 14-bit accuracy of one conversion, this sampling A/D converter is ideally suited for applications with multiplexed signal sources. The ADC3214 utilizes the latest surface-mount technologies to produce a cost-effective, high-performance part in a 2" x 3" fully shielded package. It is designed around a two-pass, subranging architecture that integrates a low distortion sample-and-hold amplifier, precision voltage reference, all the necessary timing circuitry and tri-state CMOS/TTL-compatible outputs for ease of system integration.
