LTC1598CG#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1598CG#TRPBF is a micropower, 12-bit successive approximation analog-to-digital converter featuring an 8-channel multiplexer. It operates on a single 4.5V to 5.5V supply and typically draws 320μA during conversion, dropping to 1nA in shutdown mode. The device supports a maximum sampling rate of 16.8ksps with a serial interface compatible with QSPI, SPI, and MICROWIRE protocols. Key electrical specifications include ±3/4LSB maximum differential nonlinearity (DNL), ±3LSB integral nonlinearity (INL), and a signal-to-noise plus distortion ratio of 71dB at 1kHz input.

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TR suffix indicates tape and reel packaging and the #PBF suffix confirms lead-free compliance when sourcing this component. Confirm the CG designation corresponds to the commercial temperature range of 0°C to 70°C. Ensure the specific ordering code matches the required package type and environmental rating for the target application.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1598 over the LTC1594 when eight analog input channels are required, as the LTC1594 provides only four. This device is suitable for applications requiring low power consumption and direct sensor connection without gain stages due to its high impedance inputs. Consider the LTC1598L variant if operation at 3V is necessary, as the standard LTC1598 requires a 5V supply.

Analog To Digital Converters (ADC) Part Context

The LTC1598 is part of the LTC1594/LTC1598 family of micropower sampling ADCs from Analog Devices. While the LTC1594 offers a 4-channel multiplexer in a 16-pin SO package, the LTC1598 provides an 8-channel multiplexer in a 24-pin SSOP package. Both devices share identical core ADC performance characteristics and power management features.
