LTC6253-7 2GHz, 3.5mA Gain of 7 Stable Rail-to-Rail I/O Dual Op Amp
FEATURES DESCRIPTION
n
Gain Bandwidth Product: 2GHz
The LTC®6253-7 is a dual high speed, low power, rail-to- n
–3dB Frequency (AV = 7): 160MHz
rail input/output operational amplifier. On only 3.5mA of n
Low Quiescent Current: 3.5mA Max
supply current, it features a 2GHz gain-bandwidth product, n
High Slew Rate: 500V/µs
500V/µs slew rate and a low 2.75nV/√Hz of input-referred n
Input Common Mode Range Includes Both Rails
noise. The combination of high bandwidth, high slew rate, n
Output Swings Rail-to-Rail
low power consumption and low broadband noise makes n Low Broadband Voltage Noise: 2.75nV/√Hz the LTC6253-7 ideal for lower supply voltage, high speed n Fast Output Recovery signal conditioning systems. The device is stable for closed n Supply Voltage Range: 2.5V to 5.25V loop noise gains of 7 or higher. n Input Offset Voltage: 350µV Max The LTC6253-7 maintains high efficiency performance n Large Output Current: 90mA from supply voltage levels of 2.5V to 5.25V and is fully n CMRR: 105dB specified at supplies of 2.7V and 5.0V. n Open Loop Gain: 60V/mV n Operating Temperature Range: –40°C to 125°C For applications that require power-down, the LTC6253-7 n MS10 Package with Independent Shutdown Pins offers a shutdown pin which disables the amplifier and reduces current consumption to 42µA.
APPLICATIONS
The LTC6253-7 can be used as a plug-in replacement for many commercially available op amps to reduce power or n Low Voltage, High Frequency Signal Processing to improve input/output range and performance. n Driving A/D Converters L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear n Rail-to-Rail Buffer Amplifiers Technology Corporation.
