INA332 can be buff- input resistor RLIM, as shown in Figure 7. Many input signals ered using the OPA340, as shown in Figure 5. The OPA340 are inherently current-limited to less than 10mA; therefore, a can swing within 50mV of the supply rail, driving a 600Ω load. limiting resistor is not required. The OPA340 is available in the tiny MSOP-8 package. OFFSET TRIMMING V+ Shutdown RLIM The INA332 is laser trimmed for low offset voltage. In the V + 3 7 event that external offset adjustment is required, the offset

paralleling of impedances, simplifying the gain of the circuit is to place a buffer amplifier (such as the OPA340) between the output of the INA139 or INA169 devices and the input to the ADC. Figure 10 illustrates this concept. A low-pass filter can be placed between the OPA340 output and the input to the ADC.
