Add To BomLTC2444IUHF#PBF General Description
The LTC2444/LTC2445/LTC2448/LTC2449 are 8-/16- channel (4-/8-differential) high speed 24-bit No Latency ?∑ ADCs. They use a proprietary delta-sigma architecture enabling variable speed/resolution. Through a simple 4-wire serial interface, ten speed/resolution combinations 6.9Hz/280nVRMS to 3.5kHz/25μVRMS (4kHz with external oscillator) can be selected with no latency between conversion results or shift in DC accuracy (offset, full-scale, linearity, drift). Additionally, a 2X speed mode can be selected enabling output rates up to 7kHz (8kHz if an external oscillator is used) with one cycle latency.
Features
- Up to 8 Differential or 16 Single-Ended Input Channels
- Up to 8kHz Output Rate
- Up to 4kHz Multiplexing Rate
- Selectable Speed/Resolution
- 2μVRMS Noise at 1.76kHz Output Rate
- 200nVRMS Noise at 13.8Hz Output Rate with Simultaneous 50/60Hz Rejection
- Guaranteed Modulator Stability and Lock-Up Immunity for any Input and Reference Conditions
- 0.0005% INL, No Missing Codes
- Autosleep Enables 20μA Operation at 6.9Hz
- <5μV Offset (4.5V < VCC < 5.5V, –40°C to 85°C)
- 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
- LTC2445/LTC2449 Include MUXOUT/ADCIN for External Buffering or Gain
- Tiny QFN 5mm x 7mm Package
Application
- High Speed Multiplexing
- Weight Scales
- Auto Ranging 6-Digit DVMs
- Direct Temperature Measurement
- High Speed Data Acquisition
