PCM1771PWR is a special purpose analog-to-digital converter (ADC) from Texas Instruments (TI). It is a low-power, low noise device that is well suited for use in battery-powered portable applications. The ADC has an integrated charge pump and an integrated power conditioning module for power supply isolation. It has a wide signal range, low crosstalk, and low power consumption.

The PCM1771PWR is designed to accept almost any type of input signal and convert it to a digital signal. The signal range is ±10V, allowing it to accommodate a wide range of signal sources and amplitudes. The device has a high dynamic range of 80 dB, providing excellent conversion accuracy and preventing noise from corrupting the signal. The ADC also has a differential input with an adjustable gain of 0.2 to 10 for accommodating different gain requirements. The device also has a low noise floor of less than 10µV, making it ideal for sensitive measurement applications.

The power supply of the PCM1771PWR is isolated using an integrated charge pump that supplies power to the analog inputs. This allows the device to be powered by a single voltage source while providing galvanic isolation between the analog and digital sections of the device. The charge pump also enables the device to operate at low supply voltages (1.7V to 3.6V), making it ideal for low power applications.

The PCM1771PWR is ideal for use in portable, battery-powered applications that require low power consumption and high conversion accuracy. It has a wide signal range and low crosstalk, making it well suited for high performance measurements. Its low noise floor makes it an ideal choice for sensitive measurements. In addition, its integrated charge pump and power conditioning module provides isolation between the analog and digital sections, allowing it to operate with a single voltage source and enabling low power consumption.
