400V/s Slew Rate 100MHz Gain Bandwidth Product Wide Supply Range 2.7V to 12.6V Output Swings Rail-to-Rail Input Common Mode Range Includes Ground Low Cost High Output Drive: 50mA Channel Separation: 90dB at 10MHz Specified on 3V, 5V, and 5V Supplies Input Offset Voltage: 1mV 8-Pin MSOP Package Operating Temperature Range: -40C to 85C Low Power Dissipation: 20mW Per Amplifier on Single 5V
The LT(R)6206 is a low cost dual voltage feedback amplifier that features a 100MHz gain-bandwidth product, a 400V/ s slew rate and a 50mA output current. The LT6206 has an input range which includes ground and an output which swings within 60mV of either supply rail, making it well suited for single supply operation. The LT6206 maintains its performance for supplies from 2.7V to 12.6V and is specified at 3V, 5V and 5V. The inputs can be driven beyond the supplies without damage or phase reversal of the output. Isolation between channels is high, over 90dB at 10MHz. The LT6206 is available in an 8-lead MSOP package with the standard op amp pinout. The device is specified over the commercial and industrial temperature range.

Note 1: Absolute Maximum ratings are those values beyond which the life of a device may be impaired. Note 2: The inputs are protected by back-to-back diodes. If the differential input voltage exceeds 1.4V, the input current should be limited to less than 10mA. Note 3: A heat sink may be required to keep the junction temperature below absolute maximum. This depends on the power supply voltage and how many amplifiers are shorted. Note 4: The LT6206C is guaranteed to meet specified performance from 0C to 70C and is designed, characterized and expected to meet specified performance from -40C to 85C but is not tested or QA sampled at these temperatures. The LT6206I is guaranteed to meet specified performance from -40C to 85C.
Note 5: Matching parameters are the difference between the two amplifiers of the LT6206. Note 6: This parameter is not 100% tested. Note 7: Output voltage swings are measured between the output and power supply rails. Note 8: Full power bandwidth is calculated from the slew rate measurement: FPBW = SR/2VPEAK. Note 9: There are reverse biased ESD diodes on all inputs and outputs. If these pins are forced beyond either supply, unlimited current will flow through these diodes. If the current is transient in nature and limited to less than 25mA, no damage to the device will occur.
