ADM705AR
The ADM705/ADM706/ADM707/ADM708 microprocessor
supervisory circuits are suitable for monitoring 5 V power
supplies/batteries and microprocessor activity.
The ADM705/ADM706 provide power-supply monitoring
circuitry that generate a reset output during power-up, powerdown, and brownout conditions. The reset output remains
operational with VCC as low as 1 V. Independent watchdog
monitoring circuitry is also provided. This is activated if the
watchdog input has not been toggled within 1.60 sec.
In addition, there is a 1.25 V threshold detector to warn of
power failures, to detect low battery conditions, or to monitor an
additional power supply. An active low, debounced manual reset
input (MR) is also included.
ADR381ARTZ-R2
The ADR380 and ADR381 are precise band gap voltage references with great accuracy, consistency, and low power consumption in a small footprint.
Temperature drift curvature correction procedures that are patented reduce the non - linearity of the voltage change with heat.
They are suited for 3 V to 5 V battery-powered applications because to their wide working range and low power consumption.
The ADR380 and ADR381 are low dropout voltage (LDV) micropower devices that deliver a consistent output voltage from suppliers as low as 300 mV above the output voltage. They are specified for the industrial temperature range (40°C to 85°C). The ADR380/ADR381 are available in the small three-lead SOT-23 package.

ADS1230IPWR – 20 Bit Analog to Digital Converter For Bridge Sensors
ADS1230IPWR - 20-Bit, 80SPS, 1-Ch Delta-Sigma ADC for Resistive Bridge Sensors & Weigh Scales
The ADS1230 is a 20-bit precision analog-to-digital converter (ADC). The ADS1230 provides a full front-end system for bridge application areas such as weigh scales, strain gauges, and pressure sensors thanks to an inbuilt low-noise programmable gain amplifier (PGA), onboard oscillator, and precision 20-bit delta-sigma ADC. The low-noise PGA has a gain of 64 or 128, allowing for a full-scale differential input of 39mV or 19.5mV. The delta-sigma ADC has an effective resolution of 20 bits and is made up of a 3rd order modulator and a 4th order digital filter. APPLICATIONS- Weigh Scales
- Strain Gauges
- Pressure Sensors

ADS1232IPWR -24-Bit, Delta-Sigma ADCs for Bridge Sensors
ADS1232IPWR is 24-bit precision analog-to-digital converter (ADCs). The ADS123x provides a full front-end solution for bridge sensor applications such as weigh scales, strain gauges, and pressure sensors thanks to its low-noise programmable gain amplifier (PGA), precision delta-sigma ADC, and internal oscillator. A differential input multiplexer (MUX) can receive two (ADS1232) or four (ADS1234) differential inputs. The ADS1232 also has a temperature sensor to monitor the outside temperature. The low-noise PGA supports a full scale differential input of 2.5 V, 1.25 V, 39 mV, or 19.5 mV and has a selectable gain of 1, 2, 64, or 128. The delta-sigma ADC has a maximum effective resolution of 23.5 bits and two data rates: 10 SPS (with 50-Hz and 60-Hz rejection) and 80 SPS.? directly connected to the MSP430 and other microcontrollers.
ADS7841EB
The ADS7841 is a 4-channel, 12-bit sampling Analog-toDigital Converter (ADC) with a synchronous serial interface. The resolution is programmable to either 8 bits or 12
bits. Typical power dissipation is 2mW at a 200kHz throughput rate and a 5V supply. The reference voltage (VREF) can
be varied between 100mV and VCC, providing a corresponding input voltage range of 0V to VREF. The device includes
a shutdown mode which reduces power dissipation to under
15?W. The ADS7841 is tested down to 2.7V operation
