Gain Programmable Circuit Offers Performance and Flexibility:
12/24/04 EDN Design Ideas / (added 12/04) You can use a standard precision instrumentation amplifier, such as the INA118 or AD623, as a
gain-programmable amplifier with high accuracy and wide gain range. However, the gain range of such parts is fixed at certain values,
limiting their flexibility. To solve the problem, a usual way is to use a gain-adjustable circuit controlled by a microcomputer |

Gain-of-three amplifier requires no external resistors:
8/17/06 EDN Design Ideas / (added 10/06) One IC provides wideband amplification and minimizes parts count. |

High Frequency AGC has Digital Control: 05/21/98 EDN-Design Ideas / (added
11/05) Many systems, especially communications, require AGC that functions at 50 MHz. Self-calibrating systems, such as automatic test
equipment, need this high-frequency response but also require digital control of the AGC output voltage. During the calibration cycle, the
test equipment calculates the AGC output voltage necessary to achieve the accuracy requirements and then increments the AGC.... |

Low Noise AC Amplifier has Digital Control of Gain and
Bandwidth: 02/05/04 EDN Design Ideas / (added 6/06) In low-noise analog circuits, a high-gain amplifier serves at the input to
increase the SNR. The input signal level determines the input-stage gain; low-level signals require the highest gain. It is also standard
practice in low-noise analog-signal processing to make the circuit's bandwidth as narrow as possible to pass only the useful input-signal
spectrum.... |
