Key Features
- 16-bit resolution with 0.0046% maximum linearity error and 175 ksps throughput delivering precision measurement accuracy across 8 multiplexed channels on a 3 V micropower supply
- 3.7 µs maximum conversion time per channel with SPI-compatible serial interface enabling direct connection to low-power MCUs and DSPs without external interface logic
- Micropower operation from 3 V supply with automatic shutdown between conversions extending battery life in portable data loggers, handheld instruments, and remote sensor nodes
Applications
The LTC1867LACGN#PBF is suited for precision industrial data acquisition systems, portable medical instruments, and multichannel sensor front ends where 16-bit accuracy and low power consumption must coexist on a single 3 V rail. Its 8-channel multiplexer allows a single IC to digitize temperature, pressure, flow, and current signals in process control equipment without additional analog switching components. Battery-operated environmental monitoring stations and wearable health devices use this ADC because its micropower architecture extends charge cycles while maintaining the measurement resolution required for regulatory compliance.

Frequently Asked Questions
What resolution and maximum sampling rate does the LTC1867LACGN#PBF offer for multichannel precision measurements?
The LTC1867LACGN#PBF provides 16-bit resolution and samples at up to 175 ksps, with a maximum conversion time of 3.7 µs per channel. Across all 8 channels in a round-robin scan, this translates to an effective per-channel update rate of approximately 21 ksps, which is sufficient for audio, vibration envelope, and slow process variable monitoring in industrial data acquisition systems.
How does the LTC1867LACGN#PBF achieve low power consumption and what supply voltage does it require?
The LTC1867LACGN#PBF operates from a 3 V supply and uses automatic shutdown between conversions, dropping to microampere-level standby current when idle. In a duty-cycled system sampling at 1 ksps, total average supply current can fall below 100 µA, enabling coin-cell battery operation in portable 16-bit data loggers and remote wireless sensor nodes for months without recharging.
What linearity specification does the LTC1867LACGN#PBF guarantee and how does this affect measurement accuracy in a weighing or pressure application?
The LTC1867LACGN#PBF guarantees a maximum integral nonlinearity error of 0.0046%, equivalent to approximately 3 LSB at 16 bits. For a 0 to 10 V input pressure transducer, this linearity ensures measurement errors below 0.5 mV across the full scale, meeting the accuracy requirements of class-B industrial pressure transmitters and precision laboratory weighing scales without a calibration lookup table.
For a 4-to-20 mA loop-powered industrial sensor, how does the LTC1867LACGN#PBF's 8-channel input architecture reduce system BOM compared to using multiple single-channel ADCs?
In a multichannel loop-powered transmitter, a single LTC1867LACGN#PBF replaces up to 8 discrete 16-bit ADC ICs, each of which would add a separate SPI bus, decoupling capacitors, and routing overhead. Consolidating all 8 inputs onto one 16-pin SSOP package reduces PCB area by roughly 70%, cuts component count by more than 30 parts, and lowers total converter quiescent current compared to running 8 separate converters in parallel.
