denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. Test conditions are V+ = 5V, V– = 0V, VCM = 0.5V unless otherwise noted. C, I SUFFIXES H SUFFIX SYMBOL PARAMETER CONDITIONS MIN TYP MAX MIN TYP MAX UNITS
ISC Output Short-Circuit Current Source ● 24 21 mA Sink ● 24 21 mA SR Slew Rate AV = 1 1 1 V/μs GBW Gain-Bandwidth Product RL = 100k 2.5 3.5 2.5 3.5 MHz (fTEST = 50kHz) ● 1.8 1.5 MHz F0 Phase Margin RL = 10k 70 70 Deg tS Settling Time 0.1% AV = 1, 1V Step 6 6 μs IS Supply Current No Load 340 425 340 425 μA (Per Amplifier) ● 465 490 μA Shutdown Current Shutdown, VSHDN ≤ 1.2V ● 6 μA (Per Amplifier) VS Supply Voltage Range Guaranteed by the PSRR Test ● 2.7 5.5 2.7 5.5 V Channel Separation fs = 10kHz, RL = 10k –120 –120 dB Shutdown Logic SHDN High ● 3.5 3.5 V SHDN Low ● 1.2 1.2 V THD Total Harmonic Distortion f = 10kHz, V+ = 5V, VOUT = 2VP-P, RL = 10k –90 –90 dB tON Turn-On Time VSHDN = 1.2V to 3.5V 10 10 µs tOFF Turn-Off Time VSHDN = 3.5V to 1.2V 2 2 µs SHDN Pin Current VSHDN = 0V ● 2 μA
Note 1:
Stresses beyond those listed under Absolute Maximum Ratings characterized and expected to meet specified performance from –40°C may cause permanent damage to the device. Exposure to any Absolute to 85°C but are not tested or QA sampled at these temperatures. The Maximum Rating condition for extended periods may affect device LTC6081I/LTC6082I are guaranteed to meet specified performance from reliability and lifetime. –40°C to 85°C. The LTC6081H/LTC6082H are guaranteed to meet specified
Note 2:
A heat sink may be required to keep the junction temperature performance from –40°C to 125°C. below the absolute maximum. This depends on the power supply voltage
Note 5:
Input offset drift is computed from the limits of the VOS test and how many amplifiers are shorted. divided by the temperature range. This is a conservative estimate of worst
Note 3:
The LTC6081C/LTC6082C and LTC6081I/LTC6082I are guaranteed case drift. Consult the Typical Performance Characteristics section for functional over the operating temperature range of –40°C to 85°C. more information on input offset drift. The LTC6081H/LTC6082H are guaranteed functional over the operating
Note 6:
IB guaranteed by the VS = 5V test. temperature range of –40°C to 125°C.
Note 7:
Current noise is calculated from In = √2qIB, where q = 1.6 • 10–19
Note 4:
The LTC6081C/LTC6082C are guaranteed to meet specified coulomb. performance from 0°C to 70°C. The LTC6081C/LTC6082C are designed,
Note 8:
VOS drift is guaranteed by the VS = 3V test. 60812fd 6 For more information www.linear.com/LTC6081
