Module chip

INA1 14 is a low-cost, general-purpose instrumentation amplifier that provides excellent accuracy. Its multifunctional 3-op amplifier design and small size make it an ideal choice for a wide range of applications. An external resistor can set any gain from 1 to 1000. The internal input protection can withstand up to ±40V without damage.

The laser processed INA1 14 has extremely low offset voltage (504V), extremely low drift (0.25μV/°C) and high common mode rejection (115dB when G = 1000). It can be powered by a minimum of ±2.25V, and can be powered by battery and 5V single power supply. The minimum quiescent current is 3mA.

INA1 14 adopts 8-pin plastic and SOL-16 surface mount package. Both have the characteristics of a temperature range of -40°C to 85*C.
