LTC1606AISW#PBF

Analog To Digital Converters (ADC) Overview

The LTC1606AISW#PBF is a 250ksps, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates from a single 5V supply with typical power dissipation of 75mW. The device features a ±10V bipolar input range and includes an internal precision reference and clock. Key electrical specifications include a maximum integral nonlinearity (INL) of ±2.0 LSB, a signal-to-noise ratio (SNR) of 90dB, and guaranteed no missing codes over the industrial temperature range (-40°C to +85°C). It utilizes a microprocessor-compatible 16-bit parallel output interface.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component authenticity through official Analog Devices channels or authorized distributors. Confirm the package type is 28-lead SOIC (SW) and the suffix #PBF indicates lead-free compliance. Ensure the operating environment stays within the specified -40°C to +85°C range for the 'I' grade variant.

Analog To Digital Converters (ADC) Selection Notes

Select this part for applications requiring high linearity and low noise at moderate speeds. The internal reference simplifies design but external references can be used for enhanced accuracy. Consider the 75mW power consumption against thermal constraints in the SOIC-28 package. Verify compatibility with the required ±10V input range and parallel digital interface.

Analog To Digital Converters (ADC) Part Context

The LTC1606 series includes variants with different temperature grades and packages. The 'A' suffix denotes improved DC performance compared to the standard 'C' grade. The 'I' suffix specifies the industrial temperature range. The 'SW' suffix indicates the 28-lead plastic Small Outline package. This specific part number combines the 'A' grade performance with the industrial temperature range and SOIC packaging.

Analog To Digital Converters (ADC) Replacement Considerations

The datasheet lists the LTC1606 as an improved 2nd source to AD976A and ADS7805. Direct pin-for-pin replacements should be verified against the specific performance requirements, particularly regarding input impedance and timing characteristics.
