The TLC5502-5M is a low-power ultra-high-speed
8-bit analog-to-digital converter that uses the
LinEPIC CMOS process. It utilizes the full parallel comparison (flash method) for high-speed conversion.
Because of such high-speed capability, the TLC5502-5M is suitable for motor control, high-speed signal
NC−No internal connection
processing, and video or radar signal processing.
Separate analog and digital supply pins are provided to reduce coupling between the high-speed digital
switching sections and the lower-frequency analog signal comparators. This pin partitioning minimizes crosstalk
and unwanted spurious signals.
The TLC5502-5M is characterized for operation from −55°C to 125°C.
During storage or handling, the device leads should be shorted together or the device should be placed in conductive foam. In a circuit,
unused inputs should always be connected to an appropriated logic voltage level, preferably either V
CC
or ground. Specific guidelines
for handling devices of this type are contained in the publication Guidelines for Handling Electrostatic-Discharge-Sensitive (ESDS)
Devices and Assemblies available from Texas Instruments.
