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 (A = 7): 160MHz rail input/output operational amplifier. On only 3.5mA of V n Low Quiescent Current: 3.5mA Max supply current, it features a 2GHz gain-bandwidth product, n High Slew Rate: 500V/s 500V/s 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: 350V 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 For applications that require power-down, the LTC6253-7 Operating Temperature Range: 40C to 125C n offers a shutdown pin which disables the amplifier and MS10 Package with Independent Shutdown Pins reduces current consumption to 42A. 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.
