MAX4239 Maxim, MAX4239 Datasheet - Page 4

• Manufacturer Part Number: MAX4239
• Description: The MAX4238/MAX4239 are low-noise, low-drift, ultra-high precision amplifiers that offer near-zero DC offset and drift through the use of autocorrelating zeroing techniques
• Manufacturer: Maxim

ELECTRICAL CHARACTERISTICS
(2.7V ≤ V
wise noted.) (Note 5)
Ultra-Low Offset/Drift, Low-Noise,
Precision SOT23 Amplifiers
Note 1: Guaranteed by design. Thermocouple and leakage effects preclude measurement of this parameter during production
Note 2: IN+ and IN- are gates to CMOS transistors with typical input bias current of 1pA. CMOS leakage is so small that it is
Note 3: Leakage does not include leakage through feedback resistors.
Note 4: Overload recovery time is the time required for the device to recover from saturation when the output has been
Note 5: Specifications are 100% tested at T
