What are the key features of LTC1598IG#PBF?
- 8-channel 12-bit successive-approximation ADC with serial SPI-compatible interface enabling direct connection to microcontrollers without parallel bus overhead
- ±2.5 V analog input range with 0.0061% maximum linearity error delivering high accuracy for precision sensor digitization
- 2.8 µs maximum conversion time supporting high-throughput multi-channel data acquisition at sample rates suitable for audio and industrial measurement
What is LTC1598IG#PBF used for?
The LTC1598IG#PBF is used in multi-channel data acquisition systems, industrial process monitoring, and precision instrumentation where 8 analog signals must be digitized simultaneously with 12-bit resolution. Its serial SPI interface simplifies connection to DSPs and microcontrollers in medical imaging front-ends, environmental sensors, and power quality analyzers. Engineers also deploy it in motor control feedback loops and automated test equipment where 2.8 µs conversion time and ±2.5 V input range match common transducer output levels.

Frequently Asked Questions
How many channels can LTC1598IG#PBF sample simultaneously, and what resolution does each channel provide?
The LTC1598IG#PBF provides 8 analog input channels each digitized at 12-bit resolution, yielding 4096 discrete output codes per channel. With a ±2.5 V input range, the LSB step size is approximately 1.22 mV, enabling the ADC to resolve small sensor signals without an additional gain stage in typical 5 V industrial measurement systems.
For a 4-axis motor control feedback system, how does LTC1598IG#PBF reduce SPI bus traffic compared to four separate single-channel ADCs?
Using one LTC1598IG#PBF to sample all 4 feedback channels through a multiplexed 8-channel input reduces the SPI chip-select lines from 4 to 1 and eliminates 3 separate ADC packages. At 2.8 µs maximum conversion time per channel, all 4 motor feedback channels can be digitized within 12 µs, well within a 1 kHz control loop period, while freeing PCB area and reducing BOM complexity.
What analog input voltage range does LTC1598IG#PBF accept, and does it require a signal conditioning stage for a ±1 V thermocouple amplifier output?
The LTC1598IG#PBF accepts analog inputs from -2.5 V to +2.5 V. A ±1 V thermocouple amplifier output fits comfortably within this range, using only about 40% of the full-scale span and yielding approximately 1638 codes of dynamic range at 12-bit resolution. No additional signal conditioning or range translation is needed, though a simple RC anti-aliasing filter at the input is recommended to reject high-frequency noise above the Nyquist frequency.
Is the LTC1598IG#PBF in a 36-pin SOIC a drop-in layout replacement for a 28-pin ADC with SPI interface in the same product family?
The LTC1598IG#PBF uses a 36-pin SOIC (PDSO-G36) package, which has a different pin count and physical footprint than a 28-pin SOIC. A layout replacement requires updating the PCB land pattern and pin assignment; however, the SPI-compatible serial interface is electrically similar to other LTC ADCs, so firmware changes are typically limited to channel count and register address differences rather than bus protocol rewrites.
