Linear Technology LTC2488CDE#TRPBF
- Part Number:
- LTC2488CDE#TRPBF
- Manufacturer:
- Linear Technology
- Ventron No:
- 3010673-LTC2488CDE#TRPBF
- Description:
- IC ADC 16BIT DELTA SIG 14-DFN
- Datasheet:
- LTC2488CDE#TRPBF
Description
The LTC2488 is a 16-bit, 4-channel (2-channel differential) No Latency AΣ ADC with Easy Drive technology. The patented sampling scheme eliminates dynamic input current errors and the shortcomings of on-chip buffering through automatic cancellation of differential input current. This allows large external source impedances and rail-to-rail input signals to be directly digitized while maintaining exceptional DC accuracy.
The LTC2488 includes an integrated oscillator. This device can be configured to measure an external signal from combinations of 4 analog input channels operating in single-ended or differential modes. It automatically rejects line frequencies of 50Hz and 60Hz simultaneously.
The LTC2488 allows a wide common mode, input range (0V to Vcc), independent of the reference voltage. Any combination of single-ended or differential inputs can be selected and the first conversion after a new channel selection is valid.
Features
Up to 2 differential or 4 single-ended inputs
Easy Drive technology enables rail-to-rail inputs with zero differential input current
Directly digitizes high impedance sensors with full accuracy
600nV RMS noise (0.02LSB transition noise)
GND to Vcc input/reference common mode range
Simultaneous 50Hz/60Hz rejection
2ppm INL, no missing codes
1ppm offset and 15ppm full-scale error
No latency: digital filter settles in a single cycle, even after a new channel is selected
Single supply 2.7V to 5.5V operation (0.8mW)
Internal oscillator
Tiny 4mm x 3mm DFN package
Applications
Direct sensor digitizer
Direct temperature measurement
Instrumentation
Industrial process control
