Product details
Overview
LTC2413IGN#PBF from Analog Devices (formerly Linear Technology) is a 24-bit no-latency 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, draws 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#PBF datasheet, LTC2413IGN#PBF pinout, LTC2413IGN#PBF application, or LTC2413IGN#PBF equivalent, key selection considerations include its differential input/reference architecture with GND-to-VCC common-mode range, internal oscillator eliminating external timing components, simultaneous 49–61.2Hz notch filtering, and guaranteed no missing codes at 24 bits.
Technical Context
The LTC2413IGN#PBF implements a decimating FIR digital filter synchronized to an integrated oscillator or user-supplied external clock (2.56kHz–500kHz), enabling precise 50Hz/60Hz rejection without external components. Its autocalibration engine performs offset and full-scale correction every conversion cycle, ensuring long-term stability against temperature drift and supply variation.
It supports two serial interface modes: internal SCK output (17.5kHz) or external SCK input (up to 2MHz), with CS-controlled wake-up and data output. The 3-wire SPI/MICROWIRE-compatible interface delivers 32-bit output with no latency - each data word corresponds unambiguously to the immediately preceding conversion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 24-bit with no missing codes - guarantees monotonicity and full dynamic range utilization in precision measurement. |
| INL | 2ppm of VREF - enables sub-1ppm linearity-critical applications like 6½-digit DVMs and strain-gauge transducers. |
| RMS Noise | 0.16ppm (≈0.8µV RMS at 5V reference) - supports 22.5Hz output rate with <1µV effective resolution. |
| 50/60Hz Rejection | ≥87dB from 49Hz to 61.2Hz - eliminates mains interference without software post-processing or external notch filters. |
| Supply Current | 200µA (conversion), 20µA (sleep) - enables battery-powered portable instrumentation with multi-day operation. |
| Input Range | ±0.5VREF differential, with independent INCM and REFCM from GND to VCC - simplifies ratiometric sensor interfacing and remote sensing. |
| Reference Range | 0.1V to VCC - allows flexible scaling for low-voltage sensors or high-accuracy reference sources. |
Pinout & Package
Package: 16-lead plastic SSOP (GN), 0.150" wide, JEDEC MO-153 compliant, footprint compatible with SO-8 but with 16 pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 7, 8, 9, 10, 15, 16) | Ground reference | Seven dedicated ground pins ensure low-impedance return paths for analog, digital, and reference currents - all must be connected to PCB ground plane. |
| VCC (Pin 2) | Positive supply | 2.7V–5.5V single supply; requires local 10µF tantalum + 0.1µF ceramic bypassing to Pin 1 for stable ADC performance. |
| REF+ / REF– (Pins 3, 4) | Differential reference inputs | Accept any differential voltage 0.1V–VCC; common-mode range spans full GND–VCC - enables true ratiometric bridge sensing. |
| IN+ / IN– (Pins 5, 6) | Differential analog inputs | Support ±0.5VREF input range; absolute voltage range extends beyond supply (GND−0.3V to VCC+0.3V) for overvoltage tolerance. |
| CS (Pin 11) | Active-low chip select | Wakes device from sleep, enables SDO output, and triggers new conversion on rising edge - controls entire state machine. |
| SDO (Pin 12) | 3-state serial data output | Outputs 32-bit conversion result; high-Z when CS = HIGH; status indicator during conversion/sleep when CS = LOW. |
| SCK (Pin 13) | Bidirectional serial clock | Auto-configures as output (internal clock mode) or input (external clock mode) based on power-up logic level - no register programming required. |
| FO (Pin 14) | Frequency control input | FO = GND selects internal oscillator for simultaneous 50/60Hz rejection; FO = external clock enables custom notch frequency tuning. |
Key Features
| Feature | Design Value |
|---|---|
| No-latency conversion | Single-cycle digital filter settling ensures 1:1 correspondence between conversion and output - eliminates multiplexing delay uncertainty. |
| Simultaneous 50Hz/60Hz rejection | ≥87dB rejection across 49–61.2Hz with internal oscillator - meets IEC 61000-4-7 compliance for international metering equipment. |
| Continuous auto-calibration | Offset and full-scale correction applied every conversion cycle - maintains 0.1ppm offset drift and 2.5ppm full-scale error over temperature and time. |
| Flexible reference architecture | Differential reference with independent common-mode control (REFCM) and extended input common-mode range (INCM) - supports 4-wire RTD, load cell, and thermocouple front-ends. |
| Low-power operation | 200µA active current and 20µA sleep current - enables energy harvesting and battery-backed data loggers with >1-year runtime. |

FAQ
What is the operating temperature range of the LTC2413IGN#PBF?
The LTC2413IGN#PBF is rated for –40°C to +85°C, indicated by the "I" grade suffix in the part number. This extended industrial temperature range ensures reliable operation in harsh environments such as factory floors, outdoor metering enclosures, and automotive under-hood sensor modules - unlike the commercial-grade LTC2413CGN#PBF (0°C to +70°C).
How does the LTC2413IGN#PBF achieve simultaneous 50Hz and 60Hz rejection?
The LTC2413IGN#PBF achieves simultaneous 50Hz/60Hz rejection through a fixed-frequency decimating FIR digital filter synchronized to its internal oscillator (139.8kHz). When FO is grounded, the filter's notch response spans 49–61.2Hz with ≥87dB attenuation - covering both 50Hz ±2% and 60Hz ±2% without configuration or external components.
Can the LTC2413IGN#PBF operate with a 3.3V supply and a 2.5V reference?
Yes, the LTC2413IGN#PBF fully supports 3.3V operation with a 2.5V reference. Its supply range is 2.7V–5.5V, and its reference input accepts any differential voltage from 0.1V to VCC. With VCC = 3.3V and REF+ = 2.5V / REF– = GND, the full-scale input range becomes ±1.25V, and performance specifications (e.g., 2ppm INL, 0.16ppm noise) remain valid per datasheet Conditions.
Is the LTC2413IGN#PBF pin-compatible with other devices in the LTC24xx family?
Yes, the LTC2413IGN#PBF is pin-compatible with the LTC2410 (16-bit version) and shares the same 16-lead SSOP package and pin assignments. This allows direct upgrade paths in existing designs - replacing LTC2410 with LTC2413IGN#PBF delivers 24-bit resolution and enhanced 50/60Hz rejection without PCB layout changes.
What is the purpose of the seven GND pins on the LTC2413IGN#PBF?
The seven GND pins (Pins 1, 7–10, 15, 16) provide separate low-impedance return paths for analog input, reference, digital interface, and substrate currents. They must all be connected to a solid ground plane to minimize ground bounce, reduce crosstalk, and maintain 140dB DC common-mode rejection - failure to connect all seven compromises noise performance and linearity.
