MN2310 Series

Precision, Low-Noise JFET Instrumentation Amplifiers

The MN2310 Series exceptionally low

noise characteristics and low input bias

current is made possible with the use of

a large-area discrete JFET differential

input stage. These selected and matched

JFETs exhibit superior noise characteris-

tics to those available in monolithic

JFET instrumentation amplifiers.

The JFET input stage is combined with

low-noise opamps to provide an excep-

tional bandwidth composite amplifier

with low distortion characteristics.

Precision laser-trimmed resistors facilitate

high gain accuracy without the use of

external resistors. Internal compensation

provides maximum flat gain to 1MHz.

One user-selected external capacitor is

required to precisely set the 6dB/octave

low-frequency gain roll-off, a feature

often desired in AC amplifiers.

The devices are available in factory-set

fixed gains of 30dB, 40dB, and 50dB

(MN2310, MN2311, and MN2312,

respectively) and are packaged in small

44-pin ceramic leadless chip carriers

(CLCCs). Commercial devices are

specified for 0°C to +70°C operation

while “H” models are specified for

-55°C to +125°C operation. “H/B”

models are available with environmental

stress screening while “H/B CH” models

are compliant with MIL-H-38534

requirements.

Applications for the MN2310 Series

include SONAR systems and other

piezoelectric transducer-based systems

(hydrophones, seismometers, accelerom-

eters, condenser microphones) as well

as CT scanners, Ultrasound, high

energy physics instrumentation and

other instrumentation.
