SGM620

Low Power, Low Noise, Rail-to-Rail

Output, Instrumentation Amplifier

GENERAL DESCRIPTION

FEATURES

The SGM620 is a high accuracy, high voltage

instrumentation amplifier, which is designed to set any

gain from 1 to 10000 with one external resistor. The

device works well in battery-powered applications due to

the low power consumption of 1.3mA typical quiescent

current. The SGM620 provides a SOIC-8 package which

is much smaller than discrete classical-three-OPAs

circuits.

● Single External Resistor Gain Set

(Set Gain from 1 to 10000)

● Input Offset Voltage: 150μV (MAX)

● Input Bias Current: 15nA (TYP)

● Common Mode Rejection Ratio: 105dB (TYP) (G = 10)

● Input Voltage Noise: 6nV/ Hz at 1kHz

√

● 0.1Hz to 10Hz Voltage Noise: 0.4μV_P-P

● Bandwidth: 140kHz (G = 100)

● Settling Time to 0.01%: 10μs (G = 100)

● Rail-to-Rail Output

The SGM620 provides 120ppm (MAX) non-linearity

and 150μV (MAX) low input offset voltage. The device

also features low noise, low bias current and low power.

The combination of these characteristics makes it a

good choice for applications requiring excellent DC

performance.

● Support Single or Dual Power Supplies:

4.6V to 36V or ±2.3V to ±18V

● Low Power Supply Current: 1.3mA (TYP)

● -40℃ to +125℃ Operating Temperature Range

● Available in a Green SOIC-8 Package

The SGM620 offers 6nV/ Hz low input voltage noise,

√

300fA/ Hz input current noise at 1kHz, and 0.4μV_P-Pin

√

APPLICATIONS

the 0.1Hz to 10Hz band. It is suitable for pre-amplifier

applications. The 10μs settling time to 0.01% makes

SGM620 appropriate for multiplexed applications.

Precision Current Measurement

Pressure Measurement

The SGM620 is available in a Green SOIC-8 package.

It is specified over the extended -40℃ to +125℃

temperature range.
