The q denotes specifications which apply over the full operating
temperature range.
Note 1: External power devices may require heat sinking.
Note 2: Commercial grade parts are designed to operate over the
temperature range of – 40°C to 85°C but are neither tested nor guaranteed
beyond 0°C to 70°C. Industrial grade parts specified and tested over
– 40°C and 85°C are available on special request, consult factory.
Note 3: TJ calculated from the ambient temperature TA and the power
dissipation PD according to the following formulas:
LT1166CN8: TJ = TA + (PD • 100°C/W)
LT1166CS8: TJ = TA + (PD • 150°C/W)
Note 4: ITOP = IBOTTOM
Note 5: The input resistance is typically 15MΩ when the loop is closed.
When the loop is open (current limit) the input resistance drops to 200Ω
referred to Pin 3.
Note 6: Maximum TJ can be exceeded with 50mA operating current and
simultaneous 10V and – 10V (20V total).
Note 7: Apply ±200mV to Pin 2 and measure current change in Pin 1
and 4. Pin 3 is grounded.
Note 8: PSRRCC = gmCC2 – gmCC10
gm CC2
PSRREE = gmEE2 – gmEE10
gm EE2
Note 9: For Linear Operation, Pin 1 must not be less than 2V or more than
10V from Pin 3. Similarly, Pin 4 must not be less than 2V or more than
10V from Pin 3.
