Texas Instruments Inc. (TI) has launched its 500kSps ADS8331 and ADS8332 successive approximation register (SAR) analog-to-digital converters (ADC) with true, 16-bit no missing code (NMC) precision performance. The four- and eight-channel converters operate from a 2.7V to 5.5V power supply and combine high channel count and high resolution to meet the requirements of multi-channel data acquisition applications.
The devices feature excellent AC performance with 91.5dB signal-to-noise ratio (SNR) and 101dB spurious free dynamic range (SFDR) for high accuracy and sensitivity in data acquisition applications. The ADS8331 integrates a 4:1 input multiplexer (mux) and the ADS8332 includes an 8:1 input mux with breakout, enabling designers to save up to 50 percent in board space and power draw versus a discrete implementation.
The ADS8331 and ADS8332 converters come in 24-pin, 4x4mm QFN and 24-pin TSSOP (PW) packages.
