The user-selectable dual-path digital filter allows designers to easily optimize between bandwidth and latency to maximize performance of their application. The wide-bandwidth path provides outstanding AC performance of 305kHz bandwidth path and very low passband ripple, enabling continuous measurements, such as those required in sonar, vibration monitoring and communications equipment. The low-latency path provides industry-leading settling time of only 5.5us for applications with transient inputs or when used with a multiplexer.
The ADS1672 integrates a chopper-stabilized modulator, which enables both AC performance and DC accuracy characteristics, such as the following: * AC performance: 107dB dynamic range at 625kSPS, 116dB dynamic at 78kSPS and -115dB total harmonic distortion (THD) * DC accuracy: 3ppm integral nonlinearity, 2uV/C offset drift, 2ppm/C gain drift
The ADS1672 features a selectable serial interface, either LVDS or CMOS, for easy connectivity to MCUs, DSPs or FPGAs. Operating from a single 5V analog supply and 3V digital supply, the ADS1672 is very energy efficient, dissipating only 350mW of power. It is fully specified over the industrial temperature range of -40C to 85C.
TI offers a wide variety of parts to complete the signal chain for precision industrial applications, including the OPA211 and THS4520 operational amplifiers and the REF50xx voltage references.
