Multichannel, 16-bit ADCs offer 500 kSPS throughput.

Press Release Summary:

Model ADS8331, with 4:1 input multiplexer, and ADS8332, which includes 8:1 input multiplexer with breakout, are suitable for various DAQ applications. Both successive approximation register ADCs operate from 2.7-5.5 V power supply in analog mode, while 1.65-5.5 V supply is supported in digital mode. They feature signal-to-noise ratio of 91.5 dB and spurious free dynamic range of 101 dB. Units are available in 24-pin, 4 x 4 mm QFN and 24-pin TSSOP packages.

Original Press Release:

TI Introduces Multi-Channel, 16-Bit ADCs with 500-kSPS Throughput

Low-power data converters deliver high sampling speed for portable test and measurement, data acquisition and medical applications

DALLAS - Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced the 500-kSPS 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 2.7-V to 5.5-V power supply and combine high channel count and high resolution to meet the requirements of multi-channel data acquisition applications, including test and measurement, portable, industrial and medical.

Key features and benefits

- Excellent AC performance with 91.5-dB signal-to-noise ratio (SNR) and
101-dB spurious free dynamic range (SFDR) for high accuracy and
sensitivity in data acquisition applications.

- Pin-compatible flexibility between four and eight channels enables
designers to attain high-precision performance across temperature and
various multi-channel, end-application configurations.

- 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

- Wide power supply range of 2.7 V to 5.5 V (analog) and 1.65 V to 5.5 V
(digital) allows for a wide range of use in single-cell, lithium-ion
battery applications and direct interface with low-voltage processors.

- Ease high-precision data acquisition system design with TI's THS4031
ultra low-noise, high-speed voltage feedback amplifier, the THS4031
high-speed operational amplifier evaluation module (EVM) and the
REF50xx family of low-noise, low-drift, high-precision voltage

Availability and pricing

The ADS8331 and ADS8332 converters are available now in 24-pin, 4-mm x 4-mm QFN and 24-pin TSSOP (PW) packages. Pricing in 1,000-unit quantities is $5.50 (ADS8331) and $6.50 (ADS8332).
