Description

The AD8223ARMZ is an integrated single-supply instrumentation amplifier designed for use in various applications such as thermocouple amplifiers, low power data acquisition, and industrial process controls. This component is programmable with a single resistor and can achieve a gain of 5 to 1000, and it conforms to the 8-lead industry standard pinout configuration.

Specifications and features

• Gain programmable with 1 resistor per amplifier
• Input voltage range to 150 mV below negative rail
• Maximum input bias current of 25 nA
• RTI noise @ 1kHz of 30 nV/√Hz
• Dual supply: ±2.5V to ±12.5V
• Single supply: 3V to 25V
• Maximum supply current of 600 μA

Application Scenarios

AD8223ARMZ can be used in different scenarios such as low power medical instrumentation, transducer interface, difference amplifiers, and more.

Comparison

• The AD8223ARMZ has superior user flexibility by allowing single-gain set resistor programming
• It delivers rail-to-rail output swing on a single supply (+3.0 V to +25V supplies)
• The input voltage range is broad and can go up to 150 mV below negative rail
• It is conformal to the 8-lead industry standard pinout configuration

• The maximum supply current is 600μA, which might not be enough for some high current applications
• Although it has broad input voltage range, the maximum input bias current of 25nA might not be sufficient for high precision measurements
