Accurate measuring amplifier circuit diagram

Published:2011/5/17 1:35:00 Author:Ecco | Keyword: Accurate , measuring , amplifier

INA131 is a low-cost general-purpose amplifier, the internal gain resistance corrected by the laser will make the gain error be small, it can provide the standard gain with 100 times by itself. High precision measuring amplifier is shown as Figure, the input signal is from the electrical bridge sensor (such as strain load cell, displacement measurement sensors, etc.). This connection has high interference suppression to the 50Hz power interference and high common-mode interference. If magnification is 100, it needs a higher gain, it should be increased a gain resistor RG between ①, ⑧ foot, the gain size is: G = 100 +250 kΩ / RG.   (View)

500kHs bandwidth photoelectric isolating circuit diagram composed of A-840V/F reversal module

Published:2011/5/17 1:47:00 Author:Ecco | Keyword: 500kHs , bandwidth, photoelectric isolating, reversal module

This circuit uses the A-8402V / F converter components, the linear is ± 0.05%, the maximum switching frequency is higher than 500KHZ to drive light emitting diode of optical isolator. The other A-8402V / F component can change the output of the optical isolator into a proportional DC voltage. The power supply is 12V or 5 ~ 18V. The A-840V / F components shown as the chart can form a 500kHs bandwidth optical isolation circuit.   (View)

The frequency converter circuit diagram based on TQ5638 GPS receiver

Published:2011/5/16 23:00:00 Author:Ecco | Keyword: frequency converter, GPS receiver

The chart shows a frequency converter with two modes of KPCS CDMA and GPS. IF range is 80MHz ~ 230MHz, it uses an external tuner. Low-noise amplifier (LNA) has an adjustable 3-order intercept point (IP3), so that the impact of intermodulation and intermodulation is reduced to minimum. Mixer IF is differential output form (for GPS mode, it can be single-ended or differential output form), it has excellent linearity and low noise figure. TQ5638 uses 4mm × 4mm MLF-24 package. TQ5638 meets the TLA / EIA 98-C wireless communication standard and it is suitable for KPCS CDMA and A-GPS.   (View)
