LINEARITY ~0.005%, G = 10 AND 100

~0.02%, G = 1 AND 1000

GAIN ACCURACY, UNTRIMMED ~0.5%

SETTLING TIME TO 0.01%, ALL GAINS,

LESS THAN 75µs

GAIN SWITCHING TIME, LESS THAN 100µs

Figure 42. AMP01 Makes an Excellent Programmable-Gain Instrumentation Amplifier; Combined Gain-Switching and

Settling Time to 13 Bits Falls Below 100 μs; Linearity is Better than 12 Bits over a Gain Range of 1 to 1000
