ideal for operation from a single 3V lithium battery. The MAX4239 also has a companion device, the MAX4238. The only difference is that the MAX4239 is a high bandwidth “decompensated” version of the MAX4238. The MAX4239 requires a minimum gain of 10 which we have in this circuit, so it’s better to use the higher bandwidth device. If you want to use the MAX4238 then that is possible without any circuit changes, only the bandwidth and other AC performance measurements will differ. A fixed gain of 100 is defined by precision resistors R5, and R3+R11. These

temperature becomes a function of the correction circuit and not the actual offset of the amplifier. The MAX4238 and MAX4239 have typical offset drifts of 10nV/°C and 50nV/1000 hours. Software-based offset adjustment: Zero calibration or tare measurements are examples of offset adjustment through software. The
