LHA7924GFMBI
The LHA7924 device is an I2C-compatible, 24-bit, high-precision, low-power analog-to-digital converter (ADC) in small DFN-10 and MSOP-10 packages. The LHA7924 device integrates a low-drift voltage reference and oscillator. The LHA7924 also includes a Programmable Gain Amplifier (PGA) and a digital comparator. These features, combined with a wide operating supply voltage range, make the LHA7924 ideal for power-constrained and space-constrained sensor measurement applications.
The LHA7924 can perform conversions at data rates up to 1000 samples per second (SPS). The PGA provides an input range from ±256mV to ±6.144V, enabling accurate small and large signal measurements. The LHA7924 has an input multiplexer (MUX) that enables two pairs of differential input measurements or four single-ended input measurements. Digital comparators are available in the LHA7924 for undervoltage and overvoltage detection.
LHA7924 can work in both continuous conversion mode and single-shot mode. In single-shot mode, these devices automatically power down after a single conversion; thus significantly reducing power consumption during idle periods.
