Data Acquisition - Analog to Digital Converters (ADCs) are vital components for signal processing, control, and communication in numerous industrial and scientific applications. The LTC2158IUP-14 is an integrated, high-performance monolithic 14-bit ADC optimized for signal conversion from DC to 500 kHz within a 100 kHz signal bandwidth. It is ideally suited for applications requiring low noise, high speed and high resolution in wide dynamic ranges up to 6 Vp-p. This ADC can be easily and seamlessly integrated into existing application designs.

The device is based on a switch-capacitor, delta-sigma architecture which enables it to achieve exceptional performance and reliable accuracy. With an ultra-low noise floor of only 10.3 nV/√Hz and a drift of only 0.15 ppm/K, the LTC2158IUP-14 supports a variety of applications, ranging from medical imaging and seismic sensing to industrial test and measurement and high quality audio systems.

In addition to the delta-sigma architecture, the device features an innovative power-efficient design that allows it to achieve more than 80 dB SNR, while drawing only 173 mW of power. It also has an integrated 14-bit digital low-pass filter (DLPF) with a maximum cutoff frequency of 500 kHz, enabling it to accept wide input frequency ranges and provide extremely accurate signal conversion. The LTC2158IUP-14 also offers an on-chip voltage reference for improved performance and reduced external component count.

The device incorporates an array of features specifically designed for signal acquisition applications. It offers a wide range of gain settings, including 0 dB and +1 dB, and allows for both single-ended and differential input modes. Its 14-bit data output can be easily integrated with microcontrollers and other digital signal processing (DSP) components. A mini-DIN connector allows for easy connection with oscilloscopes, spectrum analyzers and other test equipment, while the two independent power supplies provide maximum flexibility for users.

The LTC2158IUP-14 is an ideal solution for applications that require high-resolution data acquisition with minimal noise and distortion. Its fast and low power design makes it well-suited for a variety of signal processing applications, including medical imaging, seismic sensing, industrial automation, and high quality audio systems. In addition, the device is easy to use and provides excellent signal conversion performance.
