LTC1047 ELECTRICAL CHARACTERISTICS The ● denotes the specifications which apply over the full operatingtemperature range, otherwise specifications are at TA = 25 ° C. VS = ± 5V, unless otherwise noted.PARAMETERCONDlTlONSMINTYPMAXUNITS Slew Rate RL = 100k, CL = 50pF 0.2 V/µs Gain Bandwidth Product 200 kHz Supply Current/Amplifier No Load, 25°C ≤ TA ≤ 70°C 60 150 µA No Load, 0°C ≤ TA ≤ 25°C 80 275 µA Internal Sampling Frequency 680 Hz Note 1: Absolute Maximum Ratings are those values beyond which the life Note 3: These parameters are guaranteed by design. Thermocouple effects of a device may be impaired. preclude measurements of these voltage levels in high speed automatic Note 2: Connecting any terminal to voltages greater than V+ or less than V– test systems. VOS is measured to a limit determined by test equipment may cause destructive latch-up. It is recommended that no sources capability. operating from external supplies be applied prior to power-up of the Note 4: Current Noise is calculated from the formula: In = √2q • IB) where LTC1047. q = 1.6 • 10–19 Coulomb.
