MOUNTAIN VIEW, Calif.-- TelCom Semiconductor Inc. here has announced the TC3405, the second member of its low-power sigma-delta analog-to-digital converter family.
The TC3405 offers lower power consumption -- from 1.8- to 5.5-volt operation -- than competing products, and a voltage supply bus monitor with microprocessor reset output. TelCom's 16-bit Delta-Sigma A/D converter family comprises the first 16-bit ADCs capable of operating at extremely low power consumption off a wide range of supply voltages, according to Don Ashley, advanced products marketing manager at TelCom.
"Flexibility is built into this device by offering the microprocessor interface to scale the sampling rate and resolution to fit the application desired," Ashley said.
The TC3405 has one differential and three single ended inputs with a built-in multiplexer. The device is aimed at precision applications such as handheld medical instruments, process control and data acquisition systems, digital voltage meters and other consumer electronic devices. Using a 2-wire MicroPort digital interface, data is scanned out of the TC3405 serial data interface and the conversion rate can be scaled from 16 bits at 8 samples per econd up to 10 bits at 512 samples per second.
The TC3405 is available in 16-pin PDIP and QSOP packages. For 1,000 pieces, the pricing starts at $3.22 each.
