Product details
Overview
LTC2413IGN#TRPBF from Analog Devices (formerly Linear Technology) is a 24-bit micropower delta-sigma analog-to-digital converter with simultaneous 50Hz/60Hz rejection, 2ppm INL, 0.16ppm RMS noise, and single-cycle settling time. It operates from 2.7V to 5.5V, consumes only 200µA in conversion mode, and targets high-precision sensor digitization in industrial instrumentation and international power-grid-synchronized measurement systems.
For engineers reviewing the LTC2413IGN#TRPBF datasheet, LTC2413IGN#TRPBF pinout, LTC2413IGN#TRPBF application, or LTC2413IGN#TRPBF equivalent, key selection considerations include its guaranteed no-missing-codes 24-bit resolution, differential input/reference support with GND-to-VCC common-mode range, integrated oscillator eliminating external timing components, and ±40°C to +85°C industrial temperature rating.
Technical Context
The LTC2413IGN#TRPBF implements a decimating FIR digital filter with internal oscillator-based clocking, enabling true simultaneous 50Hz and 60Hz line-frequency rejection without external components. Its autocalibration architecture performs offset and full-scale correction in every conversion cycle, ensuring long-term stability against temperature drift and supply variation.
It supports two serial interface modes: internal SCK output (SCK pin driven by internal oscillator at ~17.5kHz) and external SCK input (user-provided clock up to 2MHz), both compatible with SPI/MICROWIRE protocols. The FO pin selects between internal oscillator (50/60Hz rejection) and external clock (user-defined notch frequency at fEOSC/2560).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 24-bit with no missing codes - guarantees monotonicity and full dynamic range utilization for precision metrology. |
| INL | 2ppm of VREF - enables 16-bit+ effective accuracy even at full scale, critical for strain-gauge and load-cell applications. |
| RMS Noise | 0.16ppm of VREF - translates to sub-100nV RMS noise with 5V reference, supporting 6½-digit DVM-level resolution. |
| Supply Current | 200µA (conversion), 20µA (sleep) - allows battery-powered operation for >1 year in low-duty-cycle sensor nodes. |
| Input Rejection | 87dB normal-mode rejection from 49Hz to 61.2Hz - ensures immunity to AC mains interference in global deployments. |
| Common-Mode Range | GND to VCC on both inputs and reference - permits direct interfacing with unbuffered transducers and remote sensing topologies. |
| Operating Temp | –40°C to +85°C - qualified for industrial process control, automotive cabin sensors, and outdoor environmental monitoring. |
Pinout & Package
Package: 16-lead plastic SSOP (GN), 0.150" wide, SO-8 footprint-compatible, RoHS-compliant lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1,7,8,9,10,15,16) | Ground reference | Seven dedicated ground pins minimize ground bounce and improve PSRR; all must be connected to PCB ground plane. |
| VCC (Pin 2) | Positive supply | 2.7V–5.5V operation; requires local 10µF tantalum + 0.1µF ceramic bypass for stable conversion performance. |
| REF+, REF– (Pins 3,4) | Differential reference inputs | Accept 0.1V–VCC differential voltage; common-mode range spans full supply rail - enables ratiometric sensor interfaces. |
| IN+, IN– (Pins 5,6) | Differential analog inputs | Support –0.5VREF to +0.5VREF differential range; absolute input voltage range extends beyond rails (GND–0.3V to VCC+0.3V). |
| CS (Pin 11) | Chip select | Active-low enable: initiates data output and wakes ADC; HIGH forces automatic sleep mode for ultra-low power. |
| SDO (Pin 12) | Serial data output | Three-state output; drives conversion result MSB-first on falling SCK edge; Hi-Z when CS = HIGH. |
| SCK (Pin 13) | Serial clock | Bidirectional: outputs internal clock (~17.5kHz) or accepts external clock (≤2MHz); mode auto-detected at power-up or CS edge. |
| FO (Pin 14) | Frequency control | Selects internal oscillator (FO = GND → 50/60Hz rejection) or external clock (FO = signal → user-defined notch at fEOSC/2560). |
Key Features
| Feature | Design Value |
|---|---|
| No latency conversion | Single-cycle digital filter settling eliminates multiplexing delay - each output corresponds exactly to the most recent conversion. |
| Integrated oscillator | Eliminates crystals, capacitors, or external clocks for 50/60Hz rejection - reduces BOM count and layout complexity. |
| Per-conversion calibration | Automatic offset and full-scale correction in every cycle ensures <±0.1ppm/°C drift and <±2.5ppm total unadjusted error over temperature. |
| Flexible reference architecture | Differential reference with independent common-mode control allows remote sensing and eliminates reference buffer errors. |
| Industrial temperature grade | –40°C to +85°C operation with guaranteed specs - suitable for factory automation, energy metering, and harsh-environment instrumentation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision delta-sigma ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS1256IDBT | 24-bit, 30kSPS, SPI interface, no integrated oscillator, requires external crystal for 50/60Hz rejection | Lacks simultaneous 50/60Hz rejection; needs external clock and filtering for mains immunity | Choose when higher throughput (30kSPS vs 22.5Hz) is required and external timing components are acceptable |
| LTC2418CGN#PBF | 8-channel 24-bit delta-sigma ADC, same 50/60Hz rejection, identical pinout and register map | Provides multiplexed multi-sensor capability; shares same timing, calibration, and noise performance | Choose for multi-channel systems where channel count outweighs cost and board space constraints |
Compared with ADS1256IDBT, LTC2413IGN#TRPBF delivers guaranteed simultaneous 50/60Hz rejection without external components, while LTC2418CGN#PBF offers identical performance with 8× channel density - both alternatives trade off integration simplicity or channel count versus the single-ended, ultra-low-power profile of LTC2413IGN#TRPBF.

FAQ
What is the operating temperature range of the LTC2413IGN#TRPBF?
The LTC2413IGN#TRPBF is rated for –40°C to +85°C operation, meeting industrial temperature requirements. This specification is confirmed in the Absolute Maximum Ratings table and applies across all electrical characteristics including INL, noise, and rejection performance. The "I" suffix in the part number explicitly denotes this extended temperature grade, distinguishing it from the commercial-grade LTC2413CGN#TRPBF (0°C to 70°C).
Does the LTC2413IGN#TRPBF require external components for 50Hz/60Hz rejection?
No, the LTC2413IGN#TRPBF does not require external components for simultaneous 50Hz/60Hz rejection. When the FO pin is tied to GND, the device uses its integrated oscillator to achieve ≥87dB normal-mode rejection from 49Hz to 61.2Hz. This eliminates crystals, capacitors, or external clock sources - a key differentiator confirmed in the Features list and Typical Application diagram.
What is the reference voltage range supported by the LTC2413IGN#TRPBF?
The LTC2413IGN#TRPBF supports a differential reference voltage (VREF = REF+ – REF–) from 0.1V to VCC. Both REF+ and REF– pins accept common-mode voltages anywhere from GND to VCC, enabling flexible ratiometric configurations and direct connection to unbuffered sensors. This is explicitly stated in the Description section and Electrical Characteristics table under "Reference Differential Voltage Range".
How does the LTC2413IGN#TRPBF handle power supply variations during conversion?
The LTC2413IGN#TRPBF provides 120dB power supply rejection (PSRR) at DC and across 50/60Hz frequencies, minimizing errors caused by supply ripple. Its per-conversion autocalibration further compensates for supply-induced offset and full-scale drift. These specifications are verified in the Electrical Characteristics table under "Power Supply Rejection" and confirmed in Typical Performance Characteristic plots G30–G33.
Is the LTC2413IGN#TRPBF pin-compatible with other devices in the LTC24xx family?
Yes, the LTC2413IGN#TRPBF is pin-compatible with the LTC2410, as explicitly noted in the Features list. Both share identical 16-pin SSOP packaging, pin assignments, and functional pin definitions (e.g., FO, CS, SDO). This allows drop-in replacement in existing designs targeting lower resolution or different rejection profiles, provided the application does not require the LTC2413's enhanced 24-bit performance or improved noise floor.
