INA В® INA114 114 INA 114 Precision
INSTRUMENTATION AMPLIFIER
FEATURES DESCRIPTION в—Џ LOW OFFSET VOLTAGE: 50ВµV max The INA114 is a low cost, general purpose instrumentation amplifier offering excellent accuracy. Its versatile 3-op amp design and small size make it ideal for a
wide range of applications. в—Џ LOW DRIFT: 0.25ВµV/В°C max
в—Џ LOW INPUT BIAS CURRENT: 2nA max
в—Џ HIGH COMMON-MODE REJECTION:
115dB min
в—Џ INPUT OVER-VOLTAGE PROTECTION:
В±40V
в—Џ WIDE SUPPLY RANGE: В±2.25 to В±18V A single external resistor sets any gain from 1 to 10,000.
Internal input protection can withstand up to В±40V
without damage.
The INA114 is laser trimmed for very low offset voltage
(50ВµV), drift (0.25ВµV/В°C) and high common-mode
rejection (115dB at G = 1000). It operates with power
supplies as low as В±2.25V, allowing use in battery
operated and single 5V supply systems. Quiescent current is 3mA maximum. в—Џ LOW QUIESCENT CURRENT: 3mA max
в—Џ 8-PIN PLASTIC AND SOL-16 APPLICATIONS 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. ● BRIDGE AMPLIFIER
