High CMRR Instrumentation Amp Works With Low Supply Voltages:
10/02/03 EDN Design Ideas / (added 02/05 Modern battery-cell voltages of 3 to 3.6V require circuits that offer efficient
low-voltage operation. This Design Idea proposes an ac-coupled instrumentation-amplifier design that features high CMRR (common-mode-rejection
ratio), wide dc input-voltage tolerance, and a first-order highpass characteristic....
In-Circuit Tester: This is an in-circuit tester that to check
correctly wired. It can test a circuit board without be influenced by semiconductor parts. (electronic circuit added 10/05)
Logic Tester: This is a simple logic level tester with
pulse stretch capability. (electronic circuit added 10/05)
Lost Cost Isolation Amplifier Suits Industrial Applications: 02/03/00 EDN
- Design Ideas / (Schematic / circuit added 10/05) The circuit in Figure 1a is a low-cost isolation amplifier for instrumentation
applications that provides as much as 500V of galvanic isolation between input and output. The amplifier uses only one small, low-cost
transformer and with little modification lends itself to cost-effective multichannel applications. Input-to-output linearity is around 0.05%
for a 2V input signal. The LM385 (National Semiconductor) low-power programmable reference diode, which operates in the shunt mode, and the
dual planar BAV99 (Philips Semiconductors) diode are the major circuit components...
Lux Meter: This is a simple Lux Meter that is suitable
for beginners. (electronic circuit added 10/05)
MAX038 Function Generator: This is a function generator
that can generates 10Hz through 20MHz in six ranges. Analog output can select one of any wave forms, sine, triangle or square. TTL output can
select 50% fixed duty or variable pulse width. (Schematic / circuit added 10/05)
