TEXAS INSTRUMENTS LM7705MMEVAL Evaluation Board, Low Noise Negative Bias Generator, Turn On Time 500µs
TEXAS INSTRUMENTS
The LM7705MMEVAL evaluation board is designed to demonstrate the functionality of LM7705 low noise negative bias generator. The LM7705 is designed to be used with low voltage amplifiers to enable the amplifiers output to swing to zero volts. The −0.23 volts is used to supply the negative supply pin of an amplifier while maintaining less then 5.5V across the amplifier. Rail to rail output amplifiers cannot output zero volts when operating from a single supply voltage and can result in error accumulation due to amplifier output saturation voltage being amplified by following gain stages. A small negative supply voltage will prevent the amplifiers output from saturating at zero volts and will help maintain an accurate zero through a signal processing chain. Additionally, when an amplifier is used to drive an ADC’s input, it can output a zero voltage signal and the full input range of an ADC can be used. The LM7705 has a shutdown pin to minimise standby power consumption. 5% output voltage tolerance 26mA max output current 3V to 5.25V supply voltage range Conversion efficiency up to 98% 78µA quiescent current 20nA shutdown current 500µs turn on time Regulated output voltage −0.232V Silicon Manufacturer: Texas Instruments Silicon Core Number: LM7705 Kit Application Type: Power Management Application Sub Type: Switched Capacitor Voltage Converter Kit Contents: Evaluation Board LM7705 Product Range: - Automotive Qualifications Standard: - Features: Regulated Output Voltage -0.232V, Max Output Current 26mA, Vin 3V to 5.25V, Turn on Time 500µs SVHC: No SVHC (15-Jun-2015) Find similar products grouped by common attribute
