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 V
Note 4: Gain is defined as A = ∆V
Note 5: Output Frequency equals oscillator frequency for MAX5070A/MAX5071A. Output frequency is one-half oscillator frequency
