Analog-to-Digital converters (ADCs) are integral components of digital systems, used to convert analog signals into the digital domain. The LTC2286IUP#TRPBF is a 12-bit, low-power, single-channel SAR (Successive Approximation Register) ADC that can accept input voltages of up to 3 Vpp. The part is also available in both a TSOT and a TDFN package.

The LTC2286IUP#TRPBF is a 12-bit ADC chip which is suitable for numerous applications where low power and high accuracy are paramount. It has a very low power consumption of only 3.3 mW @ 1 MHz sampling speed or even lower power if the sampling frequency is reduced. The trade-off is that the conversion time is increased to achieve lower power. The total power dissipation of the part is 4 mW @ 3 V.

The LTC2286IUP#TRPBF is optimized for mid-band sampling rates, allowing it to achieve good accuracy when sampling at higher frequencies. This improves the performance of the part when used in applications with limited sampling rates that require high accuracy. The part is also provided with a wide range of input common-mode range, allowing it to be used in many different types of systems without the need for external biasing or level shifting.

The part is provided in a small, 10-pin TDFN or 8-pin TSOT package, making it ideal for use in applications with limited space. The part is specified for operation from -40°C to 85°C and is guaranteed for a power supply range of 2.25 V to 3.60 V.

In terms of functionality, the LTC2286IUP#TRPBF is a 12-bit ADC with an internal voltage reference. The part features a wide sampling frequency range (1.3 MHz to 8 MHz) and a low-noise differential input. The resolution of the part is up to 12 bits and it is provided with a maximum input offset voltage of ±25 mV. The LTC2286IUP#TRPBF also features an extended dynamic range, allowing it to capture signals accurately and reliably even in noisy environments.

The working principle of the LTC2286IUP#TRPBF is based on a successive approximation register (SAR). This type of ADC converts an analog signal into a digital signal using a successive series of "comparison" steps. The signal is compared with a reference voltage and the difference is quantized and stored in a register. This process is repeated until the difference between the analog signal and the reference voltage is small enough to be quantized to the desired resolution.

The LTC2286IUP#TRPBF is ideal for applications requiring single-channel data acquisition with high accuracy, low noise, and low power consumption. These include instrumentation, test and measurement equipment, industrial automation, medical instruments, control systems, and telecommunications.
