The gain of 1/5 makes the INA159 useful to couple ±10V signals to single-supply analog-to-digital converters (ADCs), particularly those operating on a single +5V supply. The on-chip resistors are laser-trimmed for accurate gain and high mon-mode rejection. Excellent temperature coefficient of resistance (TCR) tracking of the resistors maintains gain accuracy and mon-mode rejection over temperature. The input mon-mode voltage range extends beyond the positive and negative supply rails. It operates on a total of +1.8V to +5.5V single or split supplies. The INA159 reference input uses two resistors for easy mid-supply or reference biasing. The difference amplifier is the foundation of many monly-used circuits. The INA159 provides this circuit function without using an expensive external precision resistor network. The INA159 is available in an MSOP-8 surface-mount package and is specified for operation over the extended industrial temperature range, - 40°C to +125°C. 5V V+ - IN 100kΩ 20kΩ SENSE VIN +IN 100kΩ INA159 40kΩ 40kΩ REF 2 REF 1 VREF R1 100Ω REF V+ +IN C1 - IN 1000p F ADS8325 ADC DOUT DCLOCK CS Figure 1.
