The low cost INA143 and INA2143 provide this precision circuit function without using an expensive precision network. The INA143 and INA2143 are high slew rate, gain of 10V/V or 0.1V/V difference amplifiers consisting of a precision op amp with a precision resistor network. The on-chip resistors are laser trimmed for accurate gain and high common-mode rejection. Excellent TCR tracking of the resistor maintains gain accuracy and commonmode rejection over temperature. They operate over a wide supply range, ±2.25V to ±18V (+4.5V to +36V single supply), and input common-mode voltage range extends beyond the positive and negative supply rails. The single version, INA143, package is the SO-8 surface mount. The dual version, INA2143, package is the SO-14 surface mount. Both are specified for operation over the extended industrial temperature range, –40°C to +85°C. Operation is from –55°C to +125°C.

Parameters which vary significantly with operating voltage are shown in the Typical Performance Curves. The INA143 and INA2143 are high-speed difference amplifiers suitable for a wide range of general-purpose applications. Figure 1 shows the basic G = 10 configuration. The input and feedback resistors can be reversed to achieve G = 0.1, as shown in Figure 2. For applications requiring G = 1, the INA133 and INA2133 are recommended. OFFSET VOLTAGE TRIM The INA143 and INA2143 are laser trimmed for low offset voltage and drift. Most applications require no external offset adjustment. Figure 3 shows an optional circuit for trimming the output offset voltage. The output is referred to the output reference terminal (pin 1), which is normally grounded. A voltage applied to the Ref terminal will be summed with the output signal. This can be used to null offset voltage as shown in Figure 3. The source impedance of a signal applied to the Ref terminal should be less than 10Ω to maintain good common-mode rejection. Decoupling capacitors are strongly recommended for applications with noisy or high impedance power supplies. The capacitors should be placed close to the device pins as shown in Figure 1. All circuitry is completely independent in the dual version assuring lowest crosstalk and normal behavior when one amplifier is overdriven or short-circuited. As shown in Figure 1, the differential input signal is connected to pins 2 and 3. The source impedances connected to the inputs must be nearly equal to assure good commonmode rejection. A 5Ω mismatch in source impedance will degrade the common-mode rejection of a typical device to approximately 86dB (RTI). If the source has a known impedance mismatch, an additional resistor in series with the opposite input can be used to preserve good commonmode rejection. INA143 –In V2 5 R1 10kΩ R2 100kΩ 2 6 The INA143’s internal resistors are accurately ratio trimmed to match. That is, R1/R2 and R3/R4 are trimmed to equal 0.1. However, the absolute values may not be equal (R1 + R2 may be slightly different than R3 + R4). Thus, large series resistors on the input (greater than 100Ω), even if well matched, will degrade common-mode rejection. VO = 0.1 (V3 – V2) +In 1 V3 R3 10kΩ R4 100kΩ 3 FIGURE 2.
