The PCM1807PW is an analog-to-digital converter(ADC) with a differentiating transfer function, which makes it particularly suited to applications in data acquisition, audio, and other signal processing systems. This device is available in a 8-pin PDIP package and can operate from a single supply powered from 3V to 3.6V.<\p>

The PCM1807PW is a successive approximation conversion device that incorporates a fully differential input stage with a simultaneous 11-bit sampling A/D and 8-bit D/A in the same device. The PCM1807PW uses a patented Differential Step Injection Delta-Sigma (DSIDS) technique for high-resolution A/D conversion. The device has an input range of 0.8V to 2V, with single-ended or differential inputs, and supports a full-scale input voltage range of 0.4 to 1V. This device also features a voltage gate input that can be used to temporarily gate the differential input signal path, thus allowing electrodes to be switched during Acquisition.<\p>

The PCM1807PW offers excellent performance characteristics such as low power dissipation, high conversion rate and wide input dynamic range. The device can convert an analog signal in as little as 75ms, with a sampling resolution of up to 12-bits. The SNR (Signal to Noise Ratio) it achieves is typically 128dB, and the sample and hold section works with a voltage supply range of 2.7V to 5.5V. The wide bandwidth of the differential input stage also helps to achieve higher conversion rate.<\p>

The PCM1807PW is suitable for multiple applications such as data acquisition, audio and video signal processing, video effects and automated test systems. The device is also used as part of an embedded system in order to acquire data from sensors such as accelerometers, pressure sensors, gyroscopes, flow sensors and so on. In audio applications, the device can be used for audio effects, equalizers, parametric compressors and limiters, low latency DSP, and other real-time audio processing effects.<\p>

The PCM1807PW is a very versatile device that provides accurate data conversion and excellent signal-to-noise ratio in a variety of applications. Its low power consumption and wide voltage range make it particularly suitable for use in portable or battery powered systems. The device is also easy to use and provides a simple interface for connecting to external components. The PCM1807PW is therefore an ideal choice for any project requiring high accuracy, low power consumption and wide dynamic range<\p>.
