description
The TLV245x is a family of rail-to-rail input/output operational amplifiers that set a new performance point for
supply current and ac performance. These devices consume a mere 23 µA/channel while of fering 220 kHz of
gain bandwidth product; much higher than competitive devices with similar supply current levels. Along with
increased ac performance, the amplifier provides high output drive capability, solving a major shortcoming of
older micropower rail-to-rail input/output operational amplifiers. The TLV245x can swing to within 250 mV of
each supply rail while driving a 2.5-mA load. Both the inputs and outputs swing rail-to-rail for increased dynamic
range in low-voltage applications. This performance makes the TLV245x family ideal for portable medical
equipment, patient monitoring systems, and data acquisition circuits.
Three members of the family (TLV2450/3/5) offer a shutdown terminal for conserving battery life in portable
applications. During shutdown, the outputs are placed in a high-impedance state and the amplifier consumes
only 16 nA/channel. The family is fully specified at 3 V and 5 V across an expanded industrial temperature range
(–40°C to 125°C). The singles and duals are available in the SOT23 and MSOP packages, while the quads are
available in TSSOP. The TL V2450 offers an amplifier with shutdown functionality all in a 6-pin SOT23 package,
making it perfect for high density circuits.

APPLICATION INFORMATION
shutdown function
Three members of the TLV245x family (TLV2450/3/5) have a shutdown terminal for conserving battery life in
portable applications. When the shutdown terminal is tied low , the supply current is reduced to 16 nA/channel,
the amplifier is disabled, and the outputs are placed in a high impedance mode. To enable the amplifier, the
shutdown terminal can either be left floating or pulled high. When the shutdown terminal is left floating, care
should be taken to ensure that parasitic leakage current at the shutdown terminal does not inadvertently place
the operational amplifier into shutdown. The shutdown terminal threshold is always referenced to VDD/2.
Therefore, when operating the device with split supply voltages (e.g. ±2.5 V), the shutdown terminal needs to
be pulled to VDD– (not GND) to disable the operational amplifier.
The amplifier’s output with a shutdown pulse is shown in Figures 42, 43, 44, and 45. The amplifier is powered
with a single 5-V supply and configured as a noninverting configuration with a gain of 5. The amplifier turnon
and turnoff times are measured from the 50% point of the shutdown pulse to the 50% point of the output
waveform. The times for the single, dual, and quad are listed in the data tables.
Figures 46 and 47 show the amplifier’s forward and reverse isolation in shutdown. The operational amplifier is
powered by ±1.35-V supplies and configured as a voltage follower (A V = 1). The isolation performance is plotted
across frequency using 0.1-VPP, 1.5-VPP, and 2.5-VPP input signals. During normal operation, the amplifier
would not be able to handle a 2.5-VPP input signal with a supply voltage of ±1.35 V since it exceeds the
common-mode input voltage range (VICR). However, this curve illustrates that the amplifier remains in shutdown
even under a worst case scenario.
macromodel information
Macromodel information provided was derived using Microsim
Parts
, the model generation software used
with Microsim
PSpice
. The Boyle macromodel (see Note 1) and subcircuit in Figure 49 are generated using
the TLV245x typical electrical and operating characteristics at TA = 25°C. Using this information, output
simulations of the following key parameters can be generated to a tolerance of 20% (in most cases):
D
Maximum positive output voltage swing
D
Maximum negative output voltage swing
D
Slew rate
D
Quiescent power dissipation
D
Input bias current
D
Open-loop voltage amplification
D
Unity-gain frequency
D
Common-mode rejection ratio
D
Phase margin
D
DC output resistance
D
AC output resistance
D
Short-circuit output current limit
