Note 1: The input current decreases to the pA level by connecting the control terminal to GND. (Off state). The
Pull-down resistor is 500 k
.
General Note: Limits are guaranteed by production testing or correction techniques using Statistical Quality
Control (SQC) methods. Unless otherwise noted. Vtest=Vout
Typ+1V ; IL=1mA (Tj=25°C) The
operation of -30
°C-80°C is guaranteed in the design by a usual inspection.
General Note: Exceeding the “Absolute Maximum Rating “ may damage the device
General Note: Connecting a capacitor to the noise bypass pin can decrease the output noise voltage
General Note: Output noise is 0.14-0.25
V/√Hz at 1KHz : 23
75Vrms at BW400-80kHz
General Note: The ripple rejection is 84dB at 400Hz and 80dB at 1kHz.
