LTC1860IS8#PBF

Analog To Digital Converters (ADC) Overview

The LTC1860IS8#PBF is a 12-bit, 250ksps successive approximation analog-to-digital converter (ADC) in an 8-lead plastic SO package. It operates on a single 5V supply with a typical supply current of 850µA at maximum sampling rate. The device features true differential analog inputs and an adjustable reference pin. It includes sample-and-hold circuitry and automatically powers down to a typical leakage current of 1nA between conversions. The component supports SPI/MICROWIRE compatible serial I/O and is designed for high-speed data acquisition in compact, low-power systems.

Analog To Digital Converters (ADC) Feature Summary

• 12-Bit Resolution with 250ksps Sampling Rate
• Single 5V Supply Operation
• Auto Shutdown Reduces Supply Current to 2µA at 1ksps
• True Differential Inputs

Analog To Digital Converters (ADC) Applications

• High Speed Data Acquisition
• Portable or Compact Instrumentation
• Low Power Battery-Operated Instrumentation
• Isolated and/or Remote Data Acquisition

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IS8 corresponds to the 8-lead Plastic SO package and the -40°C to +85°C industrial temperature range. Confirm RoHS compliance status via manufacturer documentation. Ensure the ordering suffix matches the required tape and reel or tube packaging format for production integration.

Analog To Digital Converters (ADC) Selection Notes

Select this part for applications requiring a single-channel differential input ADC with external reference capability. Compare against the LTC1861 if two-channel multiplexing is required. Consider the LTC1864/LTC1865 for pin-compatible upgrades to 16-bit resolution. Ensure source impedance is below 200Ω or buffered by high-speed op amps to handle capacitive switching spikes.

Analog To Digital Converters (ADC) Part Context

The LTC1860IS8#PBF belongs to the LTC1860/LTC1861 family of µPower, 12-bit ADCs. It is pin-compatible with the higher-resolution LTC1864 and LTC1865 devices. The 'I' grade indicates operation from -40°C to +85°C, while the 'S8' designation specifies the narrow SOIC-8 package. This family targets portable instrumentation where power consumption and board space are critical constraints.

Analog To Digital Converters (ADC) Replacement Considerations

LTC1861IS8#PBF: Offers 2-channel MUX functionality instead of single-channel differential input. LTC1864IS8#PBF: Provides 16-bit resolution with similar form factor but higher power dissipation.
