Figure 14. Single Supply Differential Speaker Driver
High Accuracy, Single-Supply, Low Power Comparator
T he OP295/OP495 makes an accurate open-loop comparator.
With a single +5 V supply, the offset error is less than 300
μ
V. Fig-
ure 15 shows the OP295/OP495’s response time when operating
open-loop with 4 mV overdrive. It exhibits a 4 ms response time at
the rising edge and a 1.5 ms response time at the falling edge.
