Product Information
Product Overview
LTC2447IUHF#PBF is a 24bit high speed 8-channel ∆Σ ADC with selectable multiple reference input. 4-terminal switching enables multiplexed ratiometric measurements. Four sets of selectable differential inputs coupled with four sets of differential reference inputs allow multiple RTDs, bridges and other sensors to be digitized by a single converter. Fifth differential reference input can be selected for any input channel not requiring ratiometric measurements (thermocouples, voltages, current sense, etc). Flexible input multiplexer allows single-ended or differential inputs coupled with server reference input or a universal reference input. First conversion following speed, resolution, channel change or reference change is valid since there is no settling time between conversions, enabling scan rates of up to 4KHz. Application includes flow, weight scales, pressure, direct temperature measurement, gas chromatography.
- Five selectable differential reference inputs
- Four differential/eight single-ended inputs
- 4-Way MUX for multiple ratiometric measurements
- Guaranteed modulator stability and lock-up immunity for any input and reference conditions
- 0.0005% INL, no missing codes, auto sleep enables 20µA operation at 6.9Hz
- Differential input and differential reference with GND to VCC common mode range
- No latency mode, each conversion is accurate even after a new channel is selected
- Internal oscillator no external components
- Resolution is 24bits (min, 0.1V ≤ VREF ≤ VCC, –0.5 • VREF ≤ VIN ≤ 0.5 • VREF)
- 38 lead plastic QFN package, operating temperature range from -40°C to 85°C
