Introduction
The SIG5532B/34B is a low noise, low drift, and high-resolution 32-bit analog-to-digital converter (ADC) with integrated programmable gain amplifier (PGA) that offers high-accuracy measurement solutions for bridge sensors, thermocouples, and resistance temperature devices (RTD). The device contains a low noise PGA with gains selected from 1, 2, 4, 8, 16, 32, and 64, a delta-sigma (Δ-Σ) modulator, and a programmable SINC3/SINC1 digital filter. A low drift 2.5V reference is integrated on chip for accurate measurement. The output data rate from the device can be configured to 1.875, 3.75, 7.5, 15, 30, 60, 120, 240, 480, 960, 1920, and 3840SPS. This device provides channel sequencer feature to measure the differential inputs automatically. Burnout current sources are provided at the analog inputs for sensor connection diagnosis. Offset and gain calibration registers are provided with calibration command or direct register write to calibrate the ADC errors or overall system errors. SPI-compatible interface is used for device configuration and parity check is provided for data integrity. The on-chip oscillator, an external clock, or an external crystal can be used as the clock source to the device. The device can operate with bipolar ±2.375V to ±2.625V analog power supplies, or with a single 4.75V to 5.25V analog power supply. The SIG5532B is available in 20-lead TSSOP package and the SIG5534B is available in 24-lead TSSOP package. These devices are fully specified over the -40°C to +125°C temperature range.
