The Burr Brown ADS1212U is a high-resolution analog-to-digital converter (ADC) designed for precision measurement applications. It utilizes a Sigma-Delta architecture to achieve an effective resolution of 23 bits at 10Hz or 20 bits at 1000Hz.
Key electrical specifications include a wide analog input voltage range of 0V to 5V, a typical analog input impedance of 20 MΩ, and a low analog input capacitance of 5 pF. The device supports differential inputs and features a programmable gain amplifier (PGA). It operates from a power supply voltage of 4.75V to 5.25V, with typical analog and digital supply currents of 95 µA and 185 µA, respectively. The power dissipation is a mere 1.4 mW at 25°C.
This ADC is available in an 18-SOIC package suitable for surface mounting. It operates within an industrial temperature range of -40°C to 85°C. The SPI-compatible data interface simplifies integration into digital systems. Applications include industrial process control, instrumentation, smart transmitters, portable instruments, and weigh scales.
Features such as an internal/external reference, on-chip self-calibration, and a no-missing-codes specification of 22 bits at 10Hz make the ADS1212U a versatile choice for demanding data acquisition tasks.
The ADS1212U has a nominal resolution of 22 bits, with an effective resolution of 23 bits at 10Hz and 20 bits at 1000Hz.
The ADS1212U operates from a power supply voltage range of 4.75V to 5.25V.
The ADS1212U is available in an 18-SOIC package (0.295", 7.50mm Width) and is designed for surface mounting.
The ADS1212U operates within a temperature range of -40°C to 85°C.
