LTC1092ACN8#PBF

ADCs/DACs - Special Purpose Overview

The LTC1092ACN8#PBF is a single-channel, 10-bit serial I/O data acquisition system manufactured by Analog Devices Inc. It integrates a switched-capacitor successive approximation A/D core with an on-chip sample-and-hold and a unipolar analog multiplexer. The device operates from a single 5V supply or dual supplies (±5V) and features a 3-wire serial interface compatible with microprocessor ports. Key electrical specifications include a maximum total unadjusted error of –1 LSB for the A grade over temperature, a typical supply current of 1 mA, and a conversion time of approximately 2 ms. It is housed in an 8-lead PDIP package.

ADCs/DACs - Special Purpose Feature Summary

• Single-channel 10-bit SAR ADC with integrated sample-and-hold
• Unipolar conversion mode only; no bipolar capability
• 3-wire serial interface (CS, CLK, DOUT) requiring no configuration word
• Low power consumption: 1 mA typical at 5V supply

ADCs/DACs - Special Purpose Applications

• Battery-powered instrumentation systems
• Remote sensor data acquisition
• Microprocessor-based measurement systems

ADCs/DACs - Special Purpose Procurement Notes

Verify the ordering suffix #PBF indicates lead-free compliance and RoHS adherence as per Analog Devices standards. Confirm the N8 package designation corresponds to the 8-lead plastic DIP (PDIP) form factor. Ensure the AC grade specification matches the required total unadjusted error performance of –1 LSB over the operating temperature range.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a single-channel, low-power, 10-bit conversion is required without the need for external multiplexing. It is suitable for applications where the input signal is unipolar. For differential inputs or bipolar ranges, consider the LTC1091 or LTC1093 series instead. Verify that the 3-wire interface aligns with the target microcontroller's serial port capabilities.

ADCs/DACs - Special Purpose Part Context

The LTC1092 is part of the LTC1091/LTC1092/LTC1093/LTC1094 family of 10-bit data acquisition systems. It serves as a pin-for-pin upgrade for older 8-bit ADCs like the ADC0831. Unlike the LTC1091 (2-channel) or LTC1093 (6-channel), the LTC1092 provides only one analog input channel, simplifying board layout for single-point monitoring applications.
