LTC1405CGN#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1405CGN#TRPBF is a 12-bit, 5Msps sampling analog-to-digital converter (ADC) housed in a 28-lead narrow SSOP package. It operates from a single 5V or dual ±5V supply with a typical power dissipation of 115mW. The device features a high dynamic range sample-and-hold circuit, a precision internal reference, and a programmable gain amplifier (PGA) with selectable 1x or 2x gain. Key electrical specifications include an integral nonlinearity error of less than 0.35 LSB, a differential nonlinearity of less than 0.25 LSB, and a full-power bandwidth of 100MHz. At the Nyquist frequency of 2.5MHz, it achieves a signal-to-noise plus distortion ratio of 71.3dB and a spurious-free dynamic range of 85dB.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the component matches the specific Analog Devices part number LTC1405CGN#TRPBF. Confirm the package type is the 28-lead narrow SSOP (GN). Ensure the temperature grade corresponds to the 'C' suffix, indicating operation within the 0°C to 70°C commercial range. Cross-reference the manufacturer's datasheet for any updates regarding pin compatibility or electrical characteristics.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution at 5Msps is required with low power consumption. It is suitable for applications needing flexible input ranges via the internal PGA and reference programming. Consider the LTC1420 if a 10Msps sampling rate is necessary, as it is pin-compatible. Ensure the system can accommodate the 28-lead SSOP footprint and provides adequate decoupling for the VDD, VSS, and OVDD pins.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1405 family of high-speed, low-power ADCs manufactured by Analog Devices. It is designed to provide high dynamic performance in a compact package. The 'CGN' designation specifies the commercial temperature range and the 28-lead SSOP package. The '#TRPBF' suffix indicates tape and reel packaging with lead-free finish.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1420 is a pin-compatible alternative offering a 10Msps sampling rate. Verify that the increased speed meets the application requirements and that the power dissipation remains within thermal limits.
