10 Power Supply Recommendations

The THS4541-DIE is principally intended to operate with a nominal single-supply voltage of +3 V to +5 V. Supply-voltage tolerances are supported with the specified operating range of 2.7 V (10% low on a 3-V nominal supply) and 5.4 V (8% high on a 5-V nominal supply). Supply decoupling is required, as described in Section 8.1.1. Split (or bipolar) supplies can be used with the THS4541-DIE, as long as the total value across the device remains less than 5.5 V (absolute maximum).

Using a negative supply to deliver a true swing to ground output in driving SAR ADCs may be desired. While the THS4541-DIE quotes a rail-to-rail output, linear operation requires approximately a 200-mV headroom to the supply rails. One easy option for extending the linear output swing to ground is to provide the small negative supply voltage required using the LM7705 fixed –230-mV, negative-supply generator. This low-cost, fixed negative-supply generator accepts the 3-V to 5-V positive supply input used by the THS4541-DIE and provides a –230-mV supply for the negative rail. Using the LM7705 provides an effective solution, as described in Extending Rail-to-Rail Output Range for Fully Differential Amplifiers to Include True Zero Volts.
