The LTC2323IUFD-16#TRPBF is a 16-bit successive approximation register (SAR) analog-to-digital converter (ADC). It is a low power, high speed, low noise ADC with a wide operating range of 2.7V to 5.25V and an on-chip reference with adjustable and fixed external ranges.

The LTC2323IUFD-16#TRPBF excels in accurately and quickly capturing even small signals changes. It operates at an sample rate up to 3.2 MS/s and features a low input voltage noise density which allows increasing precision, even at lower resolutions and oversampling rates.

The LTC2323IUFD-16#TRPBF also features a high SNR of 94dB, a THD of 75dB and a 1LSB DNL. Its low power consumption and flexible design further contributes to its benefits. It is supplied in a compact, 10-pin MSOP package, making it a suitable choice for space-constrained applications.

This data acquisition - analog to digital converter (ADC) is suitable for many applications, such as time-division and frequency-division multiplexed, analog voltage and current sensing, mobile handset screen sensing, medical diagnostics, and high-precision measurements.

Working Principle

The LTC2323IUFD-16#TRPBF works by applying an input voltage to the SAR, which uses an internal comparator to set the bits of an internal code. Each code bit is measured in successive comparisons at the input voltage and the analog input is subsequently converted into a digital output. The ADC also features an on-chip reference, which can be adjusted via two pins or left in a fixed range of 2.0V-3.3V.

The analog input is first digitized by the ADC, which samples the voltage and generates a 16-bit output code. The LTC2323IUFD-16#TRPBF utilizes an innovative low-power architecture, with no latency and a quick conversion time of 200μs. It has a wide differential input voltage range of ±2.0V which allows for precise analog input conversions with low distortion.

The low power architecture also enables high conversion rates of up to 3.2 MS/s and a minimum standby current of 0.5mA when the device is powered down. The device also has an integrated power-down mode that reduces the supply current to 0.8uA, which is ideal for portable and energy conscious applications.

Conclusion

The LTC2323IUFD-16#TRPBF is an excellent choice for data acquisition - analog to digital converters (ADC) applications due to its low power consumption and high SNR The wide operating range of 2.7V to 5.25V, low input voltage noise density, and on-chip reference with adjustable and fixed external ranges are just a few of the benefits that this ADC offers. The fast sample rate and high SNR allow accurate and precise analog input conversion, making the LCT2323IUFD-16#TRPBF well suited for applications such as mobile handset screen sensing, medical diagnostics, and high-precision measurements.
