描述
The LTA082H is a cost-effective industry-standard operational amplifier of low power, 40 V wide
supply voltage, low noise, rail-to-rail output operational amplifiers capable of operating on supplies
ranging from+4.5 V (±2.25 V) to +40 V (±20 V). The LTAɶɾɸ. offerÜ outstanding dc precision and ac
performance, including low offset (±ɷ mV typically), low offset drift (±2 μV/°C typically), ɻʒɸɻ MHz
bandwidth, and ɸɷ nV/√Hz input voltage noise density at 10 kHz. Unique features make the LTAɶɾɸ.
high-performance operational amplifiers for high-voltage industrial applications.
The robust design of the LTA082H provides ease-of-use to the circuit designer: integrated RF/EMI
rejection filter and high electro-static discharge (ESD) protection. The LTA082H are optimized
for operation at voltages from +4.5 V (±2.25 V) to +40 V (±20 V) over the extended temperature
range of 40 °C to +125 °C.
