Introduction

AI Translation

The ADS1146, ADS1147, and ADS1148 are highly-integrated, precision, 16-bit analog-to-digital converters (ADCs). The ADS1146/7/8 feature an onboard, low-noise, programmable gain amplifier (PGA), a precision delta-sigma ADC with a single-cycle settling digital filter, and an internal oscillator. The ADS1147 and ADS1148 also provide a built-in voltage reference with 10mA output capacity, and two matched programmable current digital-to-analog converters (DACs). The ADS1146/7/8 provide a complete front-end solution for temperature sensor applications including thermal couples, thermistors, and resistance temperature detectors (RTDs). An input multiplexer supports four differential inputs for the ADS1148, two for the ADS1147, and one for the ADS1146. In addition, the multiplexer has a sensor burnout detect, voltage bias for thermocouples, system monitoring, and general-purpose digital I/Os (ADS1147 and ADS1148). The onboard, low-noise PGA provides selectable gains of 1 to 128. The delta-sigma modulator and adjustable digital filter settle in only one cycle, for fast channel cycling when using the input multiplexer, and support data rates up to 2kSPS. For data rates of 20SPS or less, both 50Hz and 60Hz interference are rejected by the filter. The ADS1146 is offered in a small TSSOP-16 package, the ADS1147 is available in a TSSOP-20 package, and the ADS1148 in a TSSOP-28 package. All three devices operate over the extended specified temperature range of -40°C to +105°C.
