DC045A

DC045A demonstration circuit features the LTC1298 micropower, 11.1ksps, 2-channel sampling 12bit A/D converter that draws only 1.25mW from a single 5V supply. illustrates the layout and bypassing techniques required to obtain optimum performance from this part. The LTC1298 demo board is designed to be easy to use and requires only a 7V to 15V supply, a clock signal, and an analogue input signal. The LTC®1298 is a micropower, 11.1ksps, two-channel sampling 12bit A/D converter that draws only 1.25mW from a single 5V supply. The LTC1298 is a very space efficient solution for A/D users. By combining a micropower 12bit A/D, sample-and-hold, two-channel multiplexer, serial port, and auto shutdown circuit into a single 8-pin SOIC package, all the data acquisition circuitry including the bypass caps occupy an area of only 0.1 square inch.

• Proven µPower 12bit ADC surface mount layout
• Actual ADC footprint only 0.1inch" including bypass capacitors
• 71dB SINAD, 84dB THD and ±0.25LSB DNL
• On-chip two-channel multiplexer
