Note 1: All devices are 100% tested at +25°C. All limits over temperature are guaranteed by design, not production tested.
Note 2: Guaranteed by design, not production tested.
Note 3: Parameter measured at trip point of latch with VFB = 0 (MAX5094 only).
Note 4: Gain is defined as A = ∆VCOMP / ∆VCS, 0 ≤ VCS ≤ 0.8V for MAX5094A/MAX5094B, 0 ≤ VCS ≤ 0.2V for
MAX5094C/MAX5094D/ MAX5095_.
Note 5: Output frequency equals oscillator frequency for MAX5094A/MAX5094C/MAX5095A. Output frequency is one-half oscillator
frequency for MAX5094B/MAX5094D/MAX5095B/MAX5095C.
