Applications Information
Functional Description
The ISL28130, ISL28230 and ISL28430 are low offset low drift operational amplifiers with a very high open loop gain (150dB). The ISL28130, ISL28230 and ISL28430 operate on a single supply range of 1.65V to 5.5V or dual supply range of ±0.825V to ±2.75V while consuming only 20µA of supply current per channel. The ISL28130, ISL28230 and ISL28430 has a 400kHz gain-bandwidth. The high open loop gain, low offset voltage, high bandwidth and low 1/f noise make the ISL28130, ISL28230 and ISL28430 ideal for precision applications.
Layout Guidelines for High Impedance Inputs
To achieve the maximum performance of the high input impedance and low offset voltage of the ISL28130, ISL28230 and ISL28430 amplifiers, care should be taken in the circuit board layout. The PC board surface must remain clean and free of moisture to avoid leakage currents between adjacent traces. Surface coating of the circuit board will reduce surface moisture and provide a humidity barrier, reducing parasitic resistance on the board.
High Gain, Precision DC-Coupled Amplifier
The circuit in Figure 22 implements a single-stage DC-coupled amplifier with an input DC sensitivity of under 100nV that is only possible using a low VOS amplifier with high open loop gain. High gain DC amplifiers operating from low voltage supplies are not practical using typical low offset precision op amps. For example, a typical precision amplifier in a gain of 10kV/V with a ±100µV VOS and offset drift 0.5µV/°C of a low offset op amp would produce a DC error of >1V with an additional 5mV/°C of temperature dependent error making it difficult to resolve DC input voltage changes in the mV range. The ±40µV max VOS and 150nV/°C of temperature drift of the ISL28130, ISL28230, ISL28430 produces a temperature stable maximum DC output error of only ±400mV with a maximum output temperature drift of 1.5mV/°C. The additional benefit of a very low 1/f noise corner frequency and some feedback filtering enables DC voltages and voltage fluctuations well below 10µV to be easily detected with a simple single stage amplifier.
CF 0.018µF 1MΩ,
Rail-to-rail Input and Output (RRIO)
The RRIO CMOS amplifier uses parallel input PMOS and NMOS that enable the inputs to swing 100mV beyond either supply rail. The inverting and non-inverting inputs do not have back-to-back input clamp diodes and are capable of maintaining high input impedance at high differential input voltages. This is effective in eliminating output distortion caused by high slew-rate input signals. The output stage uses common source connected PMOS and NMOS devices to achieve rail-to-rail output drive capability with 15mA current limit and the capability to swing to within 50mV of either rail while driving a 10kΩ load.
IN+ and IN- Protection
All input terminals have internal ESD protection diodes to both positive and negative supply rails, limiting the input voltage to within one diode beyond the supply rails. For applications where either input is expected to exceed the rails by 0.5V, an external series resistor must be used to ensure the input currents never exceed 20mA (see Figure 21).
