The LH0033 slews at 1500V/µs and exhibits excellent phase linearity up to 20MHz. LH0033 is intended to fulfill a wide range of buffer applications such as high speed line drivers, video impedance transformation, nuclear instrumentation amplifiers, op amp isolation buffers for driving reactive loads and high impedance input buffers for high speed A to Ds and comparators. In addition, the LH0033 can continuously drive 50Ω coaxial cables or be used as a yoke driver for high resolution CRT displays. This device is constructed using specially selected junction FETs and active laser trimming to achieve guaranteed performance specifications. The LH0033 is specified for operation from -55 oC to +125oC and the LH0033C is specified from -25oC to 85oC. The LH0033 is available in a 2.2W metal TO-8 package.

Specifications at temperature extremes are verified by sample testing, correlation or periodic characterization. Note 2: Specification is at 25oC junction temperature due to requirements of high speed automatic testing. Actual values at operating temperature will exceed the value at TJ = 25oC. When supply voltages are ±15V, no-load operating junction temperature may rise 40-60oC above ambient, and more under load conditions. Accordingly, VOS may change one to several mV, and IB will change significantly during warm-up. Note 3: Limits are guaranteed by sample testing, periodic characterization or correlation. Note 4: Measured in still air 7 minutes after application of power. Guaranteed through correlated automatic pulse testing. Note 5: Guaranteed through correlated automatic pulse testing at TJ = 25oC.
