The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C or as noted. Test conditions are V+ = V+A = V+D = 2.7V to 5.5V, RL = 5k,
CL = 5pF unless otherwise noted. The modulation is turned off (MOD is connected to OUT1) and PH = 8 unless otherwise specified.
RSET is defined as the resistor connected from the SET pin to the V+A pin.
electricAl chArActeristics
Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: LTC6909C and the LTC6909I are guaranteed functional over the
operating temperature range of –40°C to 85°C.
Note 3: The LTC6909C is guaranteed to meet specified performance from
0°C to 70°C. The LTC6909C is designed, characterized and expected to
meet specified performance from –40°C to 85°C but is not tested or QA
sampled at these temperatures. The LTC6909I is guaranteed to meet
specified performance from –40°C to 85°C. The LTC6909H is guaranteed
to meet specified performance from –40°C to 125°C.
