Note 2: Parameter measured at trip point of latch with V EA = 0. Note 3: Gain defined as: A = V V (I ) 0 V (I ) 0.8V PIN1 TH SNS TH SNS ∆ ; ≤≤ Note 4: Adjust V DD above the start threshold before setting at 15V. Note 5: Output frequency equals oscillator frequency for the MIC38C42 and MIC38C43. Output frequency for the MIC38C44A, and MIC38C45A equals one half the oscillator frequency. Note 6: Specification for packaged product only. |
