8-bit, low-power, 3 V, 100 Msps
Analog-to-Digital Converter (ADC)
Preliminary specification
TDA8793
FEATURES
• 8-bit low-power ADC (170 mW typical)
• 2.7 to 3.6 V operation
• Sampling rate up to 100 Msps
• Track-and-hold circuit
• CMOS/TTL compatible digital inputs and outputs
• Internal references
• Adjustable full scale range possibility with external
reference
• Power-down mode; 5 mW.
GENERAL DESCRIPTION
The TDA8793 is an 8-bit low-power Analog-to-Digital
Converter (ADC) which includes a track-and-hold circuit
and internal references. The device converts an analog
input signal, up to 100 MHz, into 8-bit binary codes at a
maximum sample rate of 100 Msps. All digital inputs and
output are TTL/CMOS compatible. A sine wave clock input
signal can also by used.
The Power-down mode enables the device power
consumption to be reduced to 5 mW.
APPLICATIONS
• Radio communications
• Digital data storage read channels
• Medical imaging
• Digital instrumentation.
