LTC1598CG#PBF

Analog To Digital Converters (ADC) Overview

The LTC1598CG#PBF is a micropower, 12-bit successive approximation analog-to-digital converter featuring an 8-channel multiplexer. It operates on a single 4.5V to 5.5V supply and typically draws 320μA during conversion at a sampling rate of 16.8ksps. The device automatically powers down to a typical leakage current of 1nA between conversions. It utilizes a serial interface compatible with QSPI, SPI, and MICROWIRE protocols for data transfer. The component is housed in a 24-lead SSOP package and supports ratiometric applications or external reference inputs.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with guaranteed ±3/4LSB maximum differential nonlinearity (DNL).
• Integrated 8-channel analog multiplexer with separate MUXOUT and ADCIN pins.
• Micropower consumption: 320μA typical active current and 1nA shutdown current.
• Serial I/O interface compatible with standard microprocessor communication protocols.

Analog To Digital Converters (ADC) Applications

• Battery-operated systems requiring low power consumption.
• Remote data acquisition networks.
• Isolated data acquisition systems.
• Temperature measurement circuits.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix #PBF indicates lead-free packaging compliance. Confirm the CG suffix corresponds to the commercial temperature range of 0°C to 70°C. Ensure the 24-pin SSOP package form factor matches the target PCB footprint requirements before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-channel input multiplexing capability is required alongside 12-bit precision. It is suitable for designs operating strictly on a 5V supply rail. Consider the LTC1598L variants if a 3V supply operation is necessary instead of the standard 5V specification provided by the CG series.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1594/LTC1598 family of micropower sampling A/D converters. The LTC1598 specifically provides 8 channels, whereas the LTC1594 variant offers 4 channels. Both share identical core ADC architecture and power management features but differ in multiplexer channel count and package pinout configurations.
