MAX038 Function
Generator: This is a function generator that can generates 10Hz through 20MHz in six ranges. Analog output can select one of any waveforms, sine, triangle or square. TTL output can
select 50% fixed duty or variable pulse width. (added 10/05) |

Opamp
Doubles as Instrumentation Amp: 09/15/94 EDN-Design Ideas / (added 4/02) The circuit in Fig 1 shows an ordinary, off-the-shelf, general-purpose op amp configured as an instrumentation
amplifier. Such a configuration yields an instrumentation amplifier having higher bandwidth than currently available dedicated instrumentation amplifiers have. The circuit in Fig 1 has a gain
of 9 with a 3-dB bandwidth of 5 MHz for Ò5V signals. The CMRR is >80 dB at 1 MHz, and the large-signal transient response is good. The circuit is very stable. The offset voltage and
temperature coefficient of this circuit depends entirely on the specs of the op amp you choose.... |

Precision Peak
Detector uses No Precision Components: 06/10/04 EDN Design Ideas / (added 1/05) When you need a precision peak detector, you would usually implement it with one or several op amps
and a few other associated components. This technique usually works well unless your design requires operation higher than a few kilohertz. |
