LT1800 80MHz, 25V/µs Low Power Rail-to-Rail Input and Output Precision Op Amp
FEATURES DESCRIPTION
n
Gain Bandwidth Product: 80MHz
The LT®1800 is a low power, high speed rail-to-rail input and n
Input Common Mode Range Includes Both Rails
output operational amplifi er with excellent DC performance. n
Output Swings Rail-to-Rail
The LT1800 features reduced supply current, lower input n
Low Quiescent Current: 2mA Max
offset voltage, lower input bias current and higher DC gain n
Input Offset Voltage: 350μV Max
than other devices with comparable bandwidth. n
Input Bias Current: 250nA Max
The LT1800 has an input range that includes both supply n Low Voltage Noise: 8.5nV/√Hz rails and an output that swings within 20mV of either n Slew Rate: 25V/μs supply rail to maximize the signal dynamic range in low n Common Mode Rejection: 105dB supply applications. n Power Supply Rejection: 97dB n The LT1800 maintains its performance for supplies from Open-Loop Gain: 85V/mV n 2.3V to 12.6V and is specifi ed at 3V, 5V and ±5V supplies. Operating Temperature Range: –40°C to 85°C n The inputs can be driven beyond the supplies without Available in the 8-Pin SO and 5-Pin Low Profi le damage or phase reversal of the output. (1mm) ThinSOT™ Packages The LT1800 is available in the 8-pin SO package with the standard op amp pinout and in the 5-pin TSOT-23

package. For dual and quad versions of the LT1800, see n Low Voltage, High Frequency Signal Processing the LT1801/LT1802 data sheet. The LT1800 can be used n Driving A/D Converters as a plug-in replacement for many op amps to improve n Rail-to-Rail Buffer Amplifi ers input/output range and performance. n Active Filters L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear n Video Line Driver Technology Corporation.
