LTC1606AISW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1606AISW#TRPBF is a 250ksps, 16-bit sampling analog-to-digital converter (ADC) from Analog Devices. It operates on a single 5V supply with typical power dissipation of 75mW. The device features a ±10V bipolar input range and includes an internal sample-and-hold, precision reference, switched-capacitor SAR architecture, and trimmed internal clock. Key electrical specifications include a signal-to-noise ratio of 90dB, integral nonlinearity of ±2.0LSB maximum, 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 that the #TR suffix indicates tape and reel packaging and the #PBF suffix confirms lead-free status. Confirm the 'AI' designation corresponds to the -40°C to +85°C industrial operating temperature range as specified in the ordering information section of the datasheet.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution at 250ksps is required within a single 5V supply constraint. The internal reference simplifies design by eliminating external components for standard applications. Ensure the PCB layout separates analog and digital grounds to maintain the specified 90dB SINAD performance.

Analog To Digital Converters (ADC) FAQ

What is the full-scale input voltage range?

The full-scale input range is ±10V, determined by the internal 2.5V reference multiplied by four.

How is the conversion cycle initiated?

Conversion starts when both CS and R/C are driven low for at least 40ns, or by a falling edge on CS if R/C is already low.

Can the internal reference be bypassed?

Yes, an external reference can be applied to the REF pin (Pin 3) to override the internal 2.5V reference for improved accuracy.
