The LTC2203IUK is a 12-bit, 200ksps successive approximation register (SAR) analog-to-digital converter (ADC) optimized for low power, low cost, and small size. It has excellent low-power performance with a 25 mW power dissipation while operating at 100 ksps with a 3 V analog power supply. The device is ideal for data acquisition and portable battery-powered applications that require low power and high dynamic range performance. The flexible design of the LTC2203IUK allows for multiple applications and fast conversion rates, making it an ideal choice for any portable data acquisition system.

The LTC2203IUK is a single-slope ADC that converts an input voltage into a digital code. It consists of an amplifier, comparator, SAR logic, and an internal reference. The SAR logic is designed to measure the difference between an input voltage and an internal reference voltage. Depending on the magnitude of this difference, the SAR logic will either adjust the voltage to match the reference or determines the number of bits to be set. The SAR logic is controlled by the application or microcontroller, which sets the digital output codes according to the input voltage.

The LTC2203IUK is ideal for applications such as precision multichannel data acquisition, low-cost thermocouple measurements, battery measurements, and various other low-cost, low-power analog-to-digital applications. The versatile digital interface of the LTC2203IUK allows it to be easily interfaced with a wide variety of microcontrollers, DSPs, and FPGAs. The low power consumption of the ADC makes it suitable for use in handheld, portable and battery-powered applications. The high accuracy and stability of the LTC2203IUK ensures excellent data acquisition performance, even in noisy environments.

In addition to its superb analog-to-digital performance, the LTC2203IUK also has excellent power management features. The device can be configured to enter low power sleep mode when idle, allowing for battery powered applications to conserve power and extend battery life. Other power management features include low-power digital input/output options, low-power digital reference, and shutoff modes. These features help maximize the overall power efficiency of the device and reduce the total system cost.

The small form factor and low-power consumption of the LTC2203IUK makes it an excellent choice for any data acquisition or data conversion application. Its flexibility makes it suitable for a variety of applications and its wide range of power management features help reduce system costs and improve total system power efficiency. Whether for precision measurements, low-cost thermocouple measurements, battery measurements, or other analog-to-digital conversion projects, the LTC2203IUK is the ideal choice.
