LOG101AIDE4

TEXAS INSTRUMENTS  LOG101AIDE4  对数放大器, 2个放大器, 7.5 Decades, 1V / Decade, 110 µs, SOIC, 8 引脚

The is a versatile Amplifier IC that computes the logarithm or log ratio of an input current relative to a reference current. The LOG101 is tested over a wide dynamic range of input signals. In log ratio applications, a signal current can come from a photodiode and a reference current from a resistor in series with a precision external reference. The output signal at VOUT is trimmed to 1V per decade of input current allowing seven decades of input current dynamic range. Low DC offset voltage and temperature drift allow accurate measurement of low-level signals over a wide environmental temperature range.
