The MS53115 is a fast-settling, low-noise, 24bit Σ-Δ ADC that integrates an analog front-end and supports fully differential or single-ended, high-impedance bipolar ±10V voltage inputs.
The MS53115 integrates analog and digital signal conditioning blocks, allowing 8 independent settings to be configured for each analog input channel used. In multi-channel configurations, the maximum channel scan rate for settled data is 24.845kSPS (40.25μs).
This device includes a 2.5V, low-drift (±5ppm/°C) internal reference voltage source . The internal digital filter provides flexible settings. Users can choose different filter settings based on the requirements of each channel in their application.
An automatic channel sequencer supports ADC conversion for each enabled channel. The MS53115 is calibrated to achieve very high accuracy.
The MS53115 operates from a single power supply and is specified for operation from -40°C to +125°C.
