L-17D Log Video Amplifier IC
ANADYNE's Fast Ultra Low Noise Preamp; Compatible with many different input topologies for maximum flexibility.
Two More Linear Amplifiers; Integrated amplifiers allow for very low propagation delay and high dynamic range.
Eleven Log and Linear Extension Stages; Many of the stages are tunable making very precise and custom non linear transfers possible.
Direct Summing Junction for Dual LVA Circuits; Two or more L-17D's can be used in combination for even more dynamic range.
Output Amplifier Stage; Our output amplifier can drive 50 ohm cables and now comes with a short circuit protection option.
Hermetically sealed and thoroughly screened for high reliability applications.
INTEGRATED DC-COUPLED LOG VIDEO AMPLIFIER L-17D#A, L-17D#B, L-2010
|Package Size||10mmx10mm, packaged, 2x3 mm die|
|Input Rail Voltages||+/-5V to +/- 7V|
|Operating Temperature range||-55C to 95C||The L-17D is burned in under power at 150C|
|Current draws at +/-6V||32ma, I-, I+|
|Dynamic range linear input||>92dBv positive input, 80dBv negative input|
|Max dynamic range with tunnel diode||50dB|
|Max dynamic range with Schottky detector||65dB|
|Log linearity||Tunable to +/-1/3db|
|Temperature drift||<0.5dB after adjustment|
|Input voltage noise density||1.2nv/√Hz|
|Input current noise density||<1pa/√Hz|
|Risetime (10% to 90%)||8ns||With full dynamic range, faster with 2 log stages eliminated|
|Transit time (50% to50%)||8ns||Variation in transit time over full dynamic range can be tuned to <2ns|
|Pulse to CW variation||<.0.2dB||A change in pulse duration from 10 ns to 1 ms (at high duty-cycle) does not affect pulse height for DC coupled designs. For pseudo AC coupled designs 90%+ duty cycles are possible.|
|Fall time to 50mv output||<50ns (with recovery nets)|
|Max output voltage||VCC-2.1V|
