AD45DB081E-SSHN-T – ADESTO

The Analog Devices AD45DB081E-SSHN-T is a high-precision, low-noise, single-channel, 16-bit, Σ-Δ ADC with SPI interface, housed in a 16-lead LFCSP package. It operates from a single 2.7V to 5.5V supply voltage, boasting a typical input voltage range of 0V to VREF (where VREF is typically set between 2.5V and 5V). Its key specifications include a maximum input referred noise of 1.8µVrms (typical), a throughput rate of 8kSPS, and a total harmonic distortion (THD) below -90dB. The device features an internal reference, eliminating the need for external components and simplifying circuit design. The integrated serial peripheral interface (SPI) allows for easy integration with microcontrollers._x000D_

The AD45DB081E-SSHN-T excels in applications demanding high accuracy and low noise, such as precision instrumentation, industrial process control, and high-resolution data acquisition systems. Its small form factor and low power consumption make it suitable for portable and space-constrained designs. The use of a Σ-Δ architecture provides inherent linearity and rejection of high-frequency noise, offering superior performance compared to traditional flash or successive approximation ADCs in sensitive measurements. The -SSHN suffix indicates a high-temperature grade, extending its operational range.
