Part Number : INA114AP
Function : Precision Instrumentation Amplifier
Maker : Burr-Brown -> Texas Instruments
The INA114 is a low cost, general purpose instrumen
tation amplifier offering excellent accuracy. Its versa
tile 3-op amp design and small size make it ideal for a
wide range of applications.
A single external resistor sets any gain from 1 to 10,000.
Internal input protection can withstand up to ±40V
The INA114 is laser trimmed for very low offset voltage
(50µV), drift (0.25µV/°C) and high common-mode
rejection (115dB at G = 1000). It operates with power
supplies as low as ±2.25V, allowing use in battery
operated and single 5V supply systems. Quiescent cur
rent is 3mA maximum.
The INA114 is available in 8-pin plastic and SOL-16
surface-mount packages. Both are specified for the
–40°C to +85°C temperature range.
