Precision Voltage-Controlled Amplifier High Gain Adjust Range, Wide Bandwidth ("A" version indicates the higher grade part) The VCA810 is a DC-coupled, wideband, continuously variable, voltage-controlled gain amplifier. It provides a differential input to single-ended output conversion with a high-impedance gain control input used to vary the gain over a 40dB to +40dB range linear in dB/V. Operating from 5V supplies, the gain control voltage for the VCA810 will adjust the gain from 40dB at 0V input to +40dB at 2V input. Increasing the control voltage above ground will attenuate the signal path to > 80dB. Signal bandwidth and slew rate remain constant over the entire gain adjust range. This 40dB/V gain control is accurate within 1.5dB ( 0.9dB for High Grade), allowing the gain control voltage in an AGC application to be used as a Received Signal Strength Indicator (RSSI) with 1.5dB accuracy. HIGH GAIN ADJUST RANGE: +/-40dB DIFFERENTIAL IN/SINGLE-ENDED OUT LOW INPUT NOISE VOLTAGE: 2.4nV/vHz CONSTANT BANDWIDTH vs GAIN: 35MHz HIGH dB/V GAIN LINEARITY: +/-0.3dB LOW OUTPUT DC ERROR: < +/-40mV LOW SUPPLY CURRENT: 24.8mA (max for -40 C to +85 C temperature range) PRECISION ADSR ENVELOPE SHAPER / GENERATOR MUSICAL INSTRUMENT SOUND EFFECTS VOLTAGE-TUNABLE ACTIVE FILTERS (VCA810 opamp vca voltage controlled amp wideband SOIC8 was posted and is owned by: Sara Rollins) |
