Ultra-Low Noise Bias Voltage Reference Design for Microbolometer Detectors in Thermal Cameras
Uncooled microbolometer detectors require accurate and ultra-low noise bias voltages for their operation. Such requirements cannot be simply met by switching power supplies, LDO or DAC outputs. Enabled by Texas Instruments’ precision DAC, low noise precision amplifier and high PSRR, low noise LDO, this reference design demonstrates how to generate accurate and ultra-low noise programmable bias voltages and power supplies for uncooled microbolometer detectors at low cost.
