SPECIFICATIONS

After the AD620/623 single power supply module, it has been praised by the

majority of customers, mainly reflected in: exquisite and compact module, black

oil and gold, chip original authentic, excellent magnification performance, good

weak signal detection effect, convenient single power supply, and small on-board

shield cover signal interference

Module name: AD620/623 instrument programmed amplifier

Module power supply: 5V to 24V

Module size: 50mm X 50mm

Module bandwidth: The AD620/623 is lower than 50KHz at high gain and greater

than 1MHz at low gain

Module input signal type: single-ended signal or differential signal

The maximum magnification of the module is greater than 2000 times

(measured), due to the large gain resulting in large fluctuation of the waveform in

the band, it is recommended to use multi-stage amplification for high gain

Module saturation output amplitude: AC peak 10Vpp (±5Vpp)

Fixed output voltage: 5V-10V (default delivery 5V)

Module Features: The AD620 is a high-precision instrumentation amplifier that

requires only an external resistor to set the gain, which ranges from 1 to 10000.

This module can be amplified 1000 times, the circuit layout is regular, MINI,

reasonable design layout and wiring, generous materials, suitable for project

development and student competition. There is a fixed voltage output

The gain-bandwidth product of an amplifier (specified as GBWP, GBW, GBP, or GB)

is the product of the amplifier bandwidth and the gain of the bandwidth and is a

parameter used to simply measure the performance of an amplifier. At sufficiently

high frequencies, the gain-bandwidth product is a constant. For example, the

AD623 has a gain bandwidth product of 800KHz, which means that when the

frequency is 800Khz, the gain of the device drops to the unit gain. So A is equal to

1. It also shows that the amplifier can operate at a maximum frequency of 800KHz

without distorting the input signal. Since the product of gain and frequency is

determined, when the same device needs to get 10 times the gain, it can only

work at a maximum frequency of 80 kHz.
