CC2541 – 2.4GHz Bluetooth® Low Energy System-on-Chip Solution
TI CC2541 system-on-chip (SoC) is a power-optimized solution for both low energy and proprietary 2.4GHz applications. CC2541 enables robust network nodes to be built with low total bill-of-material costs. CC2541 SoC combines the excellent performance of a leading RF transceiver with an industry-standard enhanced 8051 MCU, in-system programmable flash memory, 8-KB RAM, and many other powerful supporting features and peripherals. The CC2541 is highly suited for systems where ultralow power consumption is required. This is specified by various operating modes. Short transition times between operating modes further enable low power consumption.
TPS62730 – Frequency, Synchronous Step-Down DC-DC Converter
TI TPS62730 is a high frequency synchronous step down DC-DC converter optimized for ultralow-power wireless applications. TI TPS62730 DC-DC converter is optimized to supply TI low power wireless sub 1GHz and 2.4GHz RF transceivers and System-On-Chip solutions. TI TPS62730 step down converter reduces the current consumption drawn from the battery during TX and RX mode by a highly efficient step down voltage conversion. This TI device provides up to 100mA output current and allows the use of tiny and low-cost chip inductors and capacitors.
ADS1292 – Low-Power, 2-Channel, 24-Bit Analog Front-End for Biopotential Measurement
Texas Instruments ADS1292 2-Channel, 24-Bit Analog Front End (AFE) is a multichannel, simultaneous sampling, 24-bit, delta-sigma analog-to-digital converter (ADC) with a built-in programmable gain amplifier (PGA), internal reference, and an onboard oscillator. TI ADS1292 incorporates all the features commonly required in portable, low-power medical electrocardiogram (ECG), sports, and fitness applications. This TI AFE features high levels of integration and exceptional performance, enabling the creation of scalable medical instrumentation systems at significantly reduced size, power, and overall cost. ADS1292 has a flexible input multiplexer per channel that can be independently connected to the internally-generated signals for test, temperature, and lead-off detection.
