Data Acquisition - Analog to Digital Converters (ADC) are necessary components for the conversion from analog signals to digital signals. The ISL26314FVZ-T7A is a high performance and cost-effective precision analog to digital converter. This ADC, with its excellent DC and AC specifications and low power dissipation, is well-suited for a variety of high-performance and portable applications.

The ISL26314FVZ-T7A is a single-channel, 14-bit, low power, 3V to 5.5V operation analog-to-digital converter. It is composed of two complete delta-sigma analog-to-digital converters with a sampling rate of 105Ksps or 140Ksps. It has excellent performance characteristics such as a 44dB SNR, -94dB THD, and -103dB DNL enabling it to measure signals with excellent accuracy. The device also features a serial communications port with an I2C interface and a power-down feature that conserves power when the device is not in use.

The device provides features such as internal reference options, on-chip sampling rate selection, analog input range selection, programmable gain amplifier (PGA) gain selection, synchronous serial port for serial output data, and dual threshold comparator functions. It also has an integrated comparator for limit detection applications and a low-power cycling feature that conserves power in battery powered applications.

The current-steering design of the ISL26314FVZ-T7A ensures higher accuracy, better power dissipation, and excellent dynamic performance. The device is ideal for use in applications that require precise measurements such as thermocouples, energy metering, strain gauges, flow meters, and industrial process control.
