denotes the specifications which apply over the specified internal operating temperature range. Specified as each individual output channel. TA = 25°C (Note 2), VIN = 12V and VRUN1, VRUN2 at 5V unless otherwise noted. Per the typical application in Figure 24. SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS Differential Amplifier
AV Differential Gain 1 V/V Amplifier RIN Input Resistance Measured at DIFFP Input 80 kΩ VOS Input Offset Voltage VDIFFP = VDIFFOUT = 1.2V, IDIFFOUT = 100µA 3 mV PSRR Differential Power Supply Rejection Ratio 5V < VIN < 15V 90 dB Amplifier ICL Maximum Output Current 3 mA VOUT(MAX) Maximum Output Voltage IDIFFOUT = 300µA INTVCC – 1.4 V GBW Gain Bandwidth Product 3 MHz VTEMP Diode Connected PNP I = 100µA 0.6 V TC Temperature Coefficient l –2.2 mV/C
Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 3:
Two outputs are tested separately and the same testing condition may cause permanent damage to the device. Exposure to any Absolute is applied to each output. Maximum Rating condition for extended periods may affect device
Note 4:
LTM4650-1 device is designed to operate from 400kHz to 750kHz. reliability and lifetime.
Note 5:
These parameters are tested at wafer sort.
Note 2:
The LTM4650-1 is tested under pulsed load conditions such that
Note 6:
See output current derating curves for different V T IN, VOUT and TA. J ≈ TA. The LTM4650-1E is guaranteed to meet specifications from 0°C to 125°C internal temperature. Specifications over the –40°C to 125°C internal operating temperature range are assured by design, characterization and correlation with statistical process controls. The LTM4650-1I is guaranteed over the full –40°C to 125°C internal operating temperature range. Note that the maximum ambient temperature consistent with these specifications is determined by specific operating conditions in conjunction with board layout, the rated package thermal impedance and other environmental factors.
