      APPLICATIONS INFORMATION
      DIFFERENTIAL OUTPUT
      The differential configuration of the AD8222 has the same
      excellent dc precision specifications as the single-ended output
      configuration and is recommended for applications in the
      frequency range of dc to 100 kHz.
      The circuit configuration is shown in Figure 49. The differential
      output specifications in Table 2 and Table 4 refer to this configura-
      tion only. The circuit includes an RC filter that maintains the
      stability of the loop.
      The transfer function for the differential output is:
      VDIFF_OUT = V+OUT VOUT = (V+IN VIN) × G

      Setting the Common-Mode Voltage
      The output common-mode voltage is set by the average of +IN2
      and REF2. The transfer function is
      VCM_OUT = (V+OUT + VOUT)/2 = (V+IN2 + VREF2)/2
      +IN2 and REF2 have different properties that allow the
      reference voltage to be easily set for a wide variety of applications.
      +IN2 has high impedance but cannot swing to the supply rails
      of the part. REF2 must be driven with a low impedance but can
      go 300 mV beyond the supply rails.
      A common application sets the common-mode output voltage
      to the midscale of a differential ADC. In this case, the ADC
      reference voltage is sent to the +IN2 terminal, and ground is
      connected to the REF2 terminal. This produces a common-mode
      output voltage of half the ADC reference voltage.
      2-Channel Differential Output Using a Dual Op Amp
      Another differential output topology is shown in Figure 50.
      Instead of a second in-amp, of a dual OP2177 op amp creates
      the inverted output. Because the OP2177 is packaged in an
      MSOP, this configuration allows the creation of a dual channel,
      precision differential output in-amp with little board area.
      Errors from the op amp are common to both outputs and are
      thus common mode. Errors from mismatched resistors also
      create a common-mode dc offset. Because these errors are
      common mode, they will likely be rejected by the next device
      in the signal chain.
