description (continued)
The Advanced LinCMOS
process uses a silicon-gate technology to obtain input offset voltage stability with
temperature and time that far exceeds that obtainable using metal-gate technology. This technology also makes
possible input-impedance levels that meet or exceed levels offered by top-gate JFET and expensive
dielectric-isolated devices.
The TLV2254 and TLV2254A, exhibiting high input impedance and low noise, are excellent for small-signal
conditioning for high-impedance sources such as piezoelectric transducers. Because of the low
power-dissipation levels combined with 3-V operation, these devices work well in hand-held monitoring and
remote-sensing applications. In addition, the rail-to-rail output feature with single or split supplies makes these
devices excellent choices when interfacing directly to analog-to-digital converters (ADCs). All of these features,
combined with its temperature performance make the TLV2254 family ideal for remote pressure sensors,
temperature control, active voltage-resistive (VR) sensors, accelerometers, hand-held metering, and many
other applications.
The device inputs and outputs are designed to withstand a 100-mA surge current without sustaining latch-up.
In addition, internal ESD-protection circuits prevent functional failures up to 2000 V as tested under
MIL-STD-883C, Method 3015.2. Care should be exercised in handling these devices as exposure to ESD may
result in degradation of the device parametric performance. Additional care should be exercised to prevent
V
DD+
supply-line transients under powered conditions. Transients greater than 20-V can trigger the
ESD-protection structure, inducing a low-impedance path to V
DD–
/GND. Should this condition occur, the
sustained current supplied to the device must be limited to 100 mA or less. Failure to do so could result in a
latched condition and device failure.
