Linear Technology LTC1851IFW#PBF
- Part Number:
- LTC1851IFW#PBF
- Manufacturer:
- Linear Technology
- Ventron No:
- 3017096-LTC1851IFW#PBF
- Description:
- IC ADC 12BIT 1.25MSPS 48-TSSOP
- Datasheet:
- LTC1851IFW#PBF
Description
The LTC1850 (10-bit) and LTC1851 (12-bit) are 8-channel data acquisition systems that include:
Flexible 8-channel multiplexer
1.25Msps successive approximation ADC with sample-and-hold
Internal 2.5V reference and reference buffer amplifier
Parallel output interface
The multiplexer can be configured for:
Single-ended or differential inputs
Two gain ranges
Unipolar or bipolar operation
The ADCs have a scan mode that cycles through all 8 multiplexer channels and can be programmed with a sequence of up to 16 addresses and configurations. The sequence memory can also be read back.
The reference and buffer amplifier provide pin strappable ranges of 4.096V, 2.5V, and 2.048V. The parallel output includes the conversion result and the multiplexer address. The digital outputs are powered from a separate supply for easy interface to 3V digital logic.
Features
Flexible 8-channel multiplexer
Single-ended or differential inputs
Two gain ranges plus unipolar and bipolar operation
1.25Msps sampling rate
Single 5V supply and 40mW power dissipation
Scan mode and programmable sequencer
Pin compatible with 10-bit LTC1850 and 12-bit LTC1851
True differential inputs reject common mode noise
Internal 2.5V reference
Parallel output includes MUX address
Easy interface to 3V logic
Nap and sleep shutdown modes
Applications
High speed data acquisition
Test and measurement
Imaging systems
Telecommunications
Industrial process control
