LTC1605-2CG#PBF

Analog To Digital Converters (ADC) Overview

The LTC1605-2CG#PBF is a single-supply, 16-bit, 100ksps sampling analog-to-digital converter (ADC) housed in a 28-lead SSOP package. It features a bipolar input range of ±4V and operates from a single 5V supply with typical power dissipation of 55mW. The device integrates a sample-and-hold circuit, precision reference, switched-capacitor successive approximation A/D core, and trimmed internal clock. Key electrical specifications include a typical signal-to-noise ratio of 86dB, integral nonlinearity error of ±3 LSBs, and a full-power bandwidth of 275kHz. It provides a microprocessor-compatible 16-bit parallel output interface.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #PBF indicates lead-free finish and tube packaging. Confirm the 'C' suffix denotes the commercial temperature range of 0°C to 70°C. Ensure the specific lot date code meets project requirements as manufacturing dates vary by production batch.

Analog To Digital Converters (ADC) Selection Notes

Select this model over the LTC1605-1 when a bipolar input range of ±4V is required, whereas the LTC1605-1 supports only 0V to 4V unipolar inputs. Consider external references if higher accuracy over temperature is needed beyond the internal bandgap specification. Verify that the 28-pin SSOP package fits the target PCB footprint constraints.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1605 family of low-power, high-resolution ADCs. The LTC1605-2 variant specifically addresses bipolar signal conditioning needs. It competes in the market for mid-speed, high-precision data conversion tasks where power efficiency and integrated reference functionality are critical design factors.
