Analog Devices Inc. LTC2410IGN#TRPBF

Overview

LTC2410IGN#TRPBF from Analog Devices (formerly Linear Technology) is a 24-bit micropower delta-sigma analog-to-digital converter with differential input and differential reference, 2 ppm INL, 0.16 ppm RMS noise, and single-cycle settling time. It operates from 2.7V to 5.5V, supports ratiometric sensor digitization, and delivers 110 dB 50/60 Hz notch rejection for precision weight scales and industrial process control.

For engineers reviewing the LTC2410IGN#TRPBF datasheet, LTC2410IGN#TRPBF pinout, LTC2410IGN#TRPBF application, or LTC2410IGN#TRPBF equivalent, this page provides verified specifications, SSOP-16 package details, SPI-compatible 3-wire interface behavior, temperature-rated performance (–40°C to +85°C), and validated alternative ADCs for high-accuracy DC measurement systems.

Technical Context

The LTC2410IGN#TRPBF implements a decimating FIR-based delta-sigma modulator with on-chip auto-calibration that performs offset and full-scale correction every conversion cycle. Its internal oscillator eliminates external timing components while enabling programmable 50 Hz or 60 Hz line-frequency rejection via the FO pin.

It accepts differential reference voltages from 0.1 V to V_CC, supports independent input and reference common-mode ranges (GND to V_CC), and achieves >140 dB DC common-mode rejection. The 3-wire digital interface operates in internal or external SCK mode without configuration registers.

FAQ

What is the operating temperature range for the LTC2410IGN#TRPBF?

The LTC2410IGN#TRPBF is specified for operation from –40°C to +85°C, as indicated by the "I" grade suffix in the part number. This industrial temperature range ensures reliable performance in harsh environments such as factory floors, outdoor instrumentation, and automotive under-hood sensing applications where thermal stability is critical. All key specifications-including INL, noise, and common-mode rejection-are guaranteed across this full range.

Does the LTC2410IGN#TRPBF require external passive components for its oscillator?

No, the LTC2410IGN#TRPBF does not require external passive components for its oscillator. It integrates a highly accurate on-chip oscillator that eliminates the need for crystals, ceramic resonators, or RC timing networks. This internal oscillator supports automatic 50 Hz or 60 Hz line-frequency rejection depending on the FO pin state, and also accepts an external clock source for custom rejection frequencies - all without external frequency-setting components.

How does the LTC2410IGN#TRPBF achieve 110 dB 50/60 Hz rejection without external filtering?

The LTC2410IGN#TRPBF achieves ≥110 dB 50/60 Hz rejection through its on-chip digital decimating FIR filter, which is precisely synchronized to its internal oscillator. When FO = V_CC or FO = GND, the filter's first null is placed exactly at 50 Hz or 60 Hz (±2%), respectively. Because the oscillator and filter are monolithically integrated and trimmed, timing jitter and component tolerance variations-common causes of degraded notch depth in discrete solutions-are eliminated, ensuring consistent rejection without external analog filters.

Can the LTC2410IGN#TRPBF interface directly with a microcontroller using standard SPI?

Yes, the LTC2410IGN#TRPBF supports standard SPI communication via its 3-wire interface (CS, SDO, SCK). In internal SCK mode, it outputs a 19.2 kHz clock on SCK and shifts out 32 bits of data on SDO; in external SCK mode, the host MCU drives SCK and reads data synchronously. No configuration registers or initialization sequences are required - the interface is inherently compatible with SPI peripherals that support variable clock polarity and phase, and it operates without software overhead for setup or calibration.

What is the purpose of the seven GND pins on the LTC2410IGN#TRPBF SSOP package?

The seven GND pins (Pins 1, 7, 8, 9, 10, 15, 16) on the LTC2410IGN#TRPBF serve to minimize ground impedance, reduce voltage drop across shared return paths, and improve power supply rejection. They provide dedicated low-inductance connections for analog ground currents, digital switching currents, and internal substrate biasing. All seven pins must be connected to a solid ground plane - failure to do so degrades PSRR, increases noise, and may cause INL or offset errors outside specification limits.
