10 Channel Analog-To-Digital (ADC) Converter – 32bit
This is a low-noise, 32-bit, 38-kSPS, 10-channel (multiplexed), delta-sigma (ΔΣ) analog-to-digital converter (ADC) module. The project consists of highly integrated ADS1263 and includes a programmable gain amplifier (PGA), a 2.5-V low-drift voltage reference, an internal oscillator, dual-sensor excitation current sources (IDAC), several system-monitoring features, and an auxiliary 24-bit ΔΣ ADC. The integrated features and excellent performance of the ADS1262 enable precision measurement of strain gauges, weight scales, pressure sensors, thermocouples, thermistors, and resistance temperature detectors (RTDs).
Analog Input Options the ADS1262 has a total of 11 analog input pins: AIN0 through AIN9 plus a common input, AINCOM. This design allows the ADS1262 to be configured for up to five differential input pairs, 10 single-ended inputs referenced to a common voltage, or a combination of single-ended and differential inputs. The flexible input multiplexer of the ADS1262 allows any two inputs to be selected for either the positive or negative ADC input. Any AINx pin can be used as a common input when measuring single-ended signals. However, AINCOM is specifically designed to serve this purpose because AINCOM can provide a bias voltage (level-shift function). This voltage biases floating sensors to help meet the common-mode voltage requirements of the AD1262 PGA. All ADC analog inputs are pinned out on the board. The supporting circuitry provides filtering and Ratiometric connections for a variety of sensors. Additionally, terminal block can be used for thermocouple inputs. Terminal block shows the connection and input filter for AINCOM.
