What are the key features of LTC1197CMS8#PBF?
- 500 ksps maximum sample rate with 10-bit resolution and 1.4 µs maximum conversion time for responsive real-time data acquisition
- Serial SPI-compatible interface simplifies digital connection to microcontrollers and FPGAs with minimal GPIO pin usage
- Compact 8-pin MSOP package with 0 V to 5 V analog input range enables low-power, space-efficient ADC integration
What is LTC1197CMS8#PBF used for?
The LTC1197CMS8#PBF is well-suited for portable data loggers, industrial sensor digitizers, and battery-monitoring systems requiring 10-bit resolution at sample rates up to 500 ksps through a simple SPI serial interface. Its 0 V to 5 V input range directly digitizes outputs from pressure sensors, current shunts, and temperature transducers without additional level shifting in 5 V systems. Motor control feedback loops and audio-frequency signal processing circuits also benefit from its 1.4 µs conversion time and minimal 8-pin MSOP footprint.

Frequently Asked Questions
What sample rate and resolution does the LTC1197CMS8#PBF deliver for industrial sensor digitization?
The LTC1197CMS8#PBF achieves up to 500 ksps with 10-bit resolution, providing 1024 discrete output codes across the 0 V to 5 V input range, equivalent to approximately 4.9 mV per LSB. At 500 ksps throughput with a 1.4 µs maximum conversion time, it is capable of accurately digitizing industrial sensor signals with bandwidths up to 250 kHz before aliasing, covering most pressure, temperature, and current sensor outputs in process control applications.
How does the SPI serial interface of the LTC1197CMS8#PBF reduce pin count compared to parallel ADCs?
The LTC1197CMS8#PBF outputs 10-bit conversion results over a 3-wire SPI-compatible serial interface using SCLK, SDO, and CS lines, requiring only 3 GPIO pins on the host microcontroller versus 10 or more GPIO pins for a parallel-bus 10-bit ADC. This pin count reduction is significant on resource-constrained microcontrollers like PIC or ARM Cortex-M0 devices, freeing GPIO pins for other peripherals in multi-sensor data acquisition systems.
How does the LTC1197CMS8#PBF perform in a battery-powered portable data logger operating from a single 5 V supply?
The LTC1197CMS8#PBF operates from a single 5 V supply with low power consumption, making it suitable for battery-powered portable instruments where the ADC draws minimal current between conversions. Its 500 ksps maximum throughput allows duty-cycled operation at lower effective sample rates such as 10 ksps or 50 ksps to reduce average power, while the SPI interface enables the host microcontroller to enter low-power sleep between conversions and wake only on each CS assertion cycle.
When would a designer choose the LTC1197CMS8#PBF over a 12-bit ADC for a motor control feedback loop?
A designer would choose the LTC1197CMS8#PBF when the motor control application requires 500 ksps sample rate at 10-bit resolution (approximately 4.9 mV/LSB on a 5 V range) and the current sensing or position feedback signal does not require the additional 2 bits of resolution that a 12-bit ADC provides. The LTC1197CMS8#PBF's smaller 8-pin MSOP footprint and lower cost make it preferable when 10-bit accuracy meets the control loop's error budget, avoiding the larger package and higher unit cost of equivalent 12-bit SAR ADCs.
