PARAMETER MEASUREMENT INFORMATION
generally measured by monitoring the distortion level of the output while increasing the frequency of a sinusoidal
input signal until the maximum frequency is found above which the output contains significant distortion. The
full-peak response is defined as the maximum output frequency, without regard to distortion, above which full
peak-to-peak output swing cannot be maintained.
Because there is no industry-wide accepted value for significant distortion, the full-peak response is specified
in this data sheet and is measured using the circuit of Figure 35. The initial setup involves the use of a sinusoidal
input to determine the maximum peak-to-peak output of the device (the amplitude of the sinusoidal wave is
increased until clipping occurs). The sinusoidal wave is then replaced with a square wave of the same
amplitude. The frequency is then increased until the maximum peak-to-peak output can no longer be maintained
(Figure 39). A square wave is used to allow a more accurate determination of the point at which the maximum
peak-to-peak output is reached.

test time
Inadequate test time is a frequent problem, especially when testing CMOS devices in a high-volume,
short-test-time environment. Internal capacitances are inherently higher in CMOS than in bipolar and BiFET
devices, and require longer test times than their bipolar and BiFET counterparts. The problem becomes more
pronounced with reduced supply levels and lower temperatures.
APPLICATION INFORMATION
single-supply operation
While the TLV234x performs well using dual-
power supplies (also called balanced or split
supplies), the design is optimized for single-
supply operation. This includes an input common-
mode voltage range that encompasses ground as
well as an output voltage range that pulls down to
ground. The supply voltage range extends down
to 2 V, thus allowing operation with supply levels
commonly available for TTL and HCMOS.
Many single-supply applications require that a
voltage be applied to one input to establish a
reference level that is above ground. This virtual
ground can be generated using two large
resistors, but a preferred technique is to use a
virtual-ground generator such as the TLE2426
(see Figure 40).
