(1) Max IB and IOS limits are specified based on characterization results. Input differential voltages greater than 2.5V can cause increased IB
(2) Typical input current noise data is specified based on design simulation results
(3) Third-order filter; bandwidth = 80 kHz at –3 dB.
(4) Short circuit current is average of sourcing and sinking short circuit currents
(5) Disable time (tOFF) and enable time (tON) are defined as the time interval between the 50% point of the signal applied to the SHDN pin and the point at which the output voltage reaches the 10% (disable) or 90% (enable) level.
(6) Full shutdown refers to the dual TLV9042S having both channels 1 and 2 disabled (SHDN1 = SHDN2 = V–) and the quad TLV9044S having all channels 1 to 4 disabled (SHDN12 = SHDN34 = V–). For partial shutdown, only one SHDN pin is exercised; in this mode, the internal biasing circuitry remains operational and the enable time is shorter.
