MAX981集成电路（IC）的比较器规格书PDF中文资料

General Description

The MAX971–MAX974 and MAX981–MAX984 single/dual/quad low-voltage comparators feature the lowest power consumption available. These micropower devices draw less than 4µA supply current over temperature (MAX971/MAX972/MAX981/MAX982), and include an internal 1.182V ±1 (MAX971/MAX973/MAX974) or ±2 (MAX981–MAX984) voltage reference and programmable hysteresis.
