Contact the factory for parts specified with wider operating temperature ranges. *The temperature grade is identified by a label on the shipping container.

Tape and reel specifications. Some packages are available in 500 unit reels through designated sales channels with #TRMPBF suffix.

**Versions of this part are available with controlled manufacturing to support the quality and reliability requirements of automotive applications. These

models are designated with a #W suffix. Only the automotive grade products shown are available for use in automotive applications. Contact your

local Analog Devices account representative for specific product ordering information and to obtain the specific Automotive Reliability reports for

these models.

ELECTRICAL CHARACTERISTICS The

l

denotes the specifications which apply over the full operating

temperature range, otherwise specifications are at TA = 25°C. Test conditions are V+ = 2.25V to 5.5V, RST = 0V for LTC6995-1,

RST = V+ for LTC6995-2, DIVCODE = 0 to 15 (NDIV = 1 to 221), RSET = 50k to 800k, RLOAD = 5k, CLOAD = 5pF unless otherwise noted.
