The LTC1861HMS#TRPBF is a field-programmable analog-to-digital converter (ADC) designed for data acquisition applications. It is part of a family of high-performance, 12-bit Analog-to-Digital Converters (ADCs). The device features wide input voltage ranges up to ±12.5V, low power consumption, fast conversion times, and on-chip sample and hold circuit.

The LTC1861HMS#TRPBF is suitable for both industrial and consumer applications, such as test and measurement, data acquisition and control, medical instrumentation, and automotive. In addition, its wide dynamic range and low power consumption makes it an ideal choice for applications requiring extended battery life.

The ADC consists of a low noise, wide dynamic range sample-and-hold amplifier, high-voltage input signal conditioning, analog signal conditioning, and 12-bit pipelined ADC. The high precision sample-and-hold amplifier enables accurate sampling of inputs as high as ±12.5V, while the low noise and low power dissipation enable extraordinary signal acquisition performance.

The signal conditioning stage consists of a two-stage amplifier and an offset and gain control network. The amplifier provides a low noise, wide dynamic range. The gain and offset control network allows the device to be tailored to the input range. The ADC itself is a 12-bit, pipelined converter that can convert wide range signals at up to 1MHz sample-rate.

The LTC1861HMS#TRPBF has two power supply pins for the analog and digital sections. The analog section is powered by a single-supply voltage that can range from 2.7V to 12V, while the digital section is powered by a separate supply voltage that can range from 2.7V to 5V. The device also has an optional low-dropout reference voltage (VREF) input.

The LTC1861HMS#TRPBF also features a flexible range of input ranges, including bipolar, unipolar, and differential inputs. It supports both single-ended and differential input modes, enabling it to be used in a variety of applications. The device has two external reference pins, allowing the user to program the device to a specific range.

The LTC1861HMS#TRPBF also features an on-board temperature sensor and an internal clock. The temperature sensor is used to measure the device\'s temperature, allowing it to automatically compensate for thermal drift. The internal clock provides an accurate system clock, allowing the ADC to be synchronized with an external system clock.

In summary, the LTC1861HMS#TRPBF is a high-performance, field-programmable analog-to-digital converter (ADC) designed for data acquisition applications. Its wide input voltage ranges and low power consumption makes it an ideal choice for applications requiring extended battery life. Its flexible input modes make it suitable for both single-ended and differential input signals. The device also features an on-board temperature sensor and an internal clock, making it suitable for a variety of applications.
