LTC2297CUP#PBF is a 12-bit, dual sample-and-hold, very low power, low noise, monolithically integrated A/D converter whose operation is based on Linear Technology\'s LTC®2418-1 technology. It features a 500ksps conversion rate and a single 5V supply. This A/D converter is ideal for portable, low power, low noise and low cost applications, such as cell phones, laptop computers and tablet computers.

The LTC2297CUP#PBF is a very low power A/D converter, designed to operate at low speeds while still providing accurate conversion rates. The power consumption is less than 150 mW at 10 MSPS, when powered by a 5V supply. The LTC2297CUP#PBF is designed to work with a 5V analog input range, allowing it to convert signals ranging in voltage from 0 V to 5 V. It has a dual-sample-and-hold architecture, allowing for simultaneous signals to be sampled for conversion.

The LTC2297CUP#PBF is typically used for a wide variety of data acquisition and analog-to-digital conversion applications, such as cell phones, digital-to-analog and analog-to-digital conversions, audio-visual systems, medical systems, home security and automation, automotive applications and process control. Its low noise and low power allow it to be used for power-sensitive applications. Additionally, the LTC2297CUP#PBF features linearity, as it can be used for accurate 16-bit conversions.

The LTC2297CUP#PBF has a flexible control interface, allowing for easy programming and control of the device. It is designed with pin-selectable reference range, logic threshold, internal clock rates and duty cycles. Additionally, it has an external clock input, allowing for synchronization with other circuits. With the use of an external reference, it can be used for accurate 16-bit conversions.

The working principle behind the LTC2297CUP#PBF is that it samples and holds an analog input voltage and then converts it to a digital signal. The device uses a charge-domain converter, which converts the analog signal by moving electrons from a source input to a destination output. To perform conversion, the A/D device applies a voltage across the input terminal, and then measures the resulting current. This current is then converted to digital representation.

In order for the LTC2297CUP#PBF to properly convert analog signals to digital, it needs to be calibrated, as different analog signals have different voltage levels and consequently different conversion paths. This is accomplished by applying a sequence of known voltages to the input and then measuring the output of the device. When the output is within an acceptable range, the device is said to be calibrated.

The LTC2297CUP#PBF is a very low power, low noise, and low cost A/D converter, which makes it an attractive choice for a wide variety of data acquisition and analog-to-digital conversion applications. Its low power consumption and flexible control interface provide great flexibility and reliability. Additionally, its accurate 16-bit conversions make it a great choice for applications needing precise conversion of analog signals.
