The ADS1231 is a high-precision, 24-bit analog-to-digital converter (ADC) designed specifically for bridge sensor applications. It features an integrated low-noise internal amplifier with a gain of 128, an onboard oscillator, and a precision third-order delta-sigma (ΔΣ) modulator, along with a low-side power switch for bridge sensors.

This comprehensive front-end solution is suitable for various applications, including weigh scales, strain gauges, and load cells. The device supports selectable data rates of 10SPS or 80SPS. The low-noise amplifier, with a gain of 128, is capable of handling a full-scale differential input of ±19.5mV while providing simultaneous rejection of both 50Hz and 60Hz signals.

The ΔΣ ADC operates at 10SPS with a resolution of 24 bits and includes a third-order modulator and a fourth-order digital filter. It supports two data rates: 10SPS (with rejection for both 50Hz and 60Hz) and 80SPS. The ADS1231 can be placed in a low-power standby mode or completely powered down. Control of the ADS1231 is achieved through dedicated pins, eliminating the need for digital register programming. Data output is facilitated via a simple, isolated serial interface that connects directly to the MSP430 and other microcontrollers.

The supply voltage range for the ADS1231 is from 3V to 5.3V, and it is packaged in an SOIC-16 format. The operating temperature range is specified from –40°C to +85°C. APPLICATIONS

The XTR111 functions as a precision voltage-to-current converter, specifically engineered for standard analog signals ranging from 0mA to 20mA or 4mA to 20mA, and can source currents up to 32mA.

The relationship between the input voltage and output current is determined by a single resistor, RSET. Additionally, the circuit can be adapted for voltage-output operation.

A high output resistance and an extensive compliance voltage range, which spans from 2V below the supply voltage, VVSP, to voltages significantly lower than ground, are provided by an external P-MOSFET transistor.

Furthermore, the adjustable subregulator output, which ranges from 3V to 15V, supplies power to additional circuitry.

The XTR111 is offered in 10-pin HVSSOP and VSON surface-mount packages.

The TJA1050 serves as the interface between the Controller Area Network (CAN) protocol controller and the physical bus. The device offers differential transmission capabilities to the bus and differential reception capabilities to the CAN controller. The TJA1050 is the third high-speed CAN transceiver developed by Philips, following the PCA82C250 and the PCA82C251.

The key differences include:

• Significantly reduced electromagnetic emissions due to optimal signal matching of CANH and CANL

• Enhanced performance in the event of an unpowered node

• Absence of a standby mode.

These features render the TJA1050 particularly well-suited for use in nodes that are in a power-down state within partially powered networks.

The M27C4001 is a 4 Mbit EPROM available in two variants: UV (ultraviolet erase) and OTP (one-time programmable). It is particularly well-suited for microprocessor systems that require large programs and is structured as 524,288 by 8 bits.

The FDIP32W (window ceramic frit-seal package) features a transparent lid that enables the user to expose the chip to ultraviolet light for erasing the bit pattern. Subsequently, a new pattern can be programmed into the device by adhering to the specified programming procedure.
