Product details
Overview
LTC2413CGN#TRPBF from Analog Devices (formerly Linear Technology) is a 24-bit no-latency delta-sigma ADC with simultaneous 50Hz/60Hz rejection, 2ppm INL, 0.16ppm RMS noise, and single-cycle settling-designed for high-precision DC measurements in weight scales, strain-gauge transducers, and 6-digit DVMs.
For engineers reviewing the LTC2413CGN#TRPBF datasheet, LTC2413CGN#TRPBF pinout, LTC2413CGN#TRPBF application, or LTC2413CGN#TRPBF equivalent, this page delivers verified specifications, SSOP-16 pin mapping, differential input/reference flexibility, internal oscillator operation, and real-world design implications for international AC-line-noise environments.
Technical Context
The LTC2413CGN#TRPBF implements a decimating FIR digital filter synchronized to an integrated oscillator, enabling deterministic 87dB minimum normal-mode rejection across 49Hz–61.2Hz without external timing components. Its autocalibration engine performs offset and full-scale correction every conversion cycle.
It supports dual clocking modes: internal oscillator (FO = GND) for fixed 50/60Hz rejection, or external clock (FO driven) for user-defined notch frequencies at fEOSC/2560 ±14% (87dB) or ±4% (110dB). The 3-wire SPI/MICROWIRE interface operates with SCK as input (external mode) or output (internal mode), selected automatically at power-up or CS edge.
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 systems. |
| INL | 2 ppm of VREF-enables ≤0.0002% linearity error in 6½-digit DVMs and calibrated sensor interfaces. |
| RMS Noise | 0.16 ppm of VREF (≈0.8 µVRMS at 5V ref)-supports sub-microvolt signal resolution in low-drift instrumentation. |
| Common Mode Rejection | 140 dB DC & 49–61.2 Hz-rejects ground-loop-induced offsets and AC-coupled interference in industrial sensors. |
| Supply Current | 200 µA in conversion mode, 20 µA in sleep-enables battery-powered portable meters with multi-year runtime. |
| Reference Range | 0.1 V to VCC differential reference-allows ratiometric sensing with low-voltage bridges or remote RTD excitation. |
| Input Common Mode Range | GND to VCC for both IN+ and IN−-permits direct connection to unbuffered transducer outputs without level-shifting. |
Pinout & Package
Package: 16-lead plastic SSOP (GN), 0°C to 70°C operating temperature range, SO-8 footprint compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 7, 8, 9, 10, 15, 16) | Ground reference | Seven dedicated ground pins minimize ground impedance and improve PSRR; all must be connected to PCB ground plane. |
| VCC (Pin 2) | Positive supply | 2.7V–5.5V operation; requires 10µF tantalum + 0.1µF ceramic bypass close to pin for stable conversion performance. |
| REF+ / REF− (Pins 3, 4) | Differential reference inputs | Accept 0.1V–VCC differential voltage; common-mode range spans full GND–VCC-enables true ratiometric bridge sensing. |
| IN+ / IN− (Pins 5, 6) | Differential analog inputs | Support –0.3V to VCC+0.3V absolute voltage; full-scale range = ±0.5×VREF-ideal for direct connection to strain gauges or thermocouples. |
| CS (Pin 11) | Active-low chip select | Wakes ADC from sleep; initiates data output; HIGH = auto-sleep after conversion; LOW-to-HIGH aborts transfer and restarts conversion. |
| SDO (Pin 12) | 3-state serial data output | Outputs 32-bit conversion result; Hi-Z when CS = HIGH; status indicator during conversion/sleep when CS = LOW. |
| SCK (Pin 13) | Bidirectional serial clock | Auto-configured as output (internal clock mode) or input (external clock mode) based on power-up/SCK edge logic state. |
| FO (Pin 14) | Frequency control input | GND = internal oscillator (50/60Hz rejection); driven = external clock (fEOSC) for programmable notch frequency. |
Key Features
| Feature | Design Value |
|---|---|
| No latency, single-cycle settling | Eliminates multiplexing delay-each conversion result corresponds directly to its input sample, enabling true time-synchronized multi-channel acquisition. |
| Simultaneous 50Hz/60Hz rejection | 87dB minimum rejection over 49–61.2Hz-ensures accurate readings in global deployments without hardware reconfiguration. |
| Integrated oscillator | Zero external components required for precision line-frequency rejection-reduces BOM cost and board area vs. crystal-based solutions. |
| Per-conversion autocalibration | Continuous offset and full-scale correction-maintains <2.5 ppm total unadjusted error over temperature and supply variation. |
| Flexible 3-wire interface | Hardware-selectable internal/external SCK mode-no register writes needed; simplifies firmware and eliminates configuration errors. |
| Wide common-mode input & reference range | GND–VCC for IN+, IN−, REF+, REF−-supports direct interfacing to unbuffered sensors, eliminating op-amp stage and associated drift. |

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 |
|---|---|---|---|
| ADS124S08IPWR | 24-bit, 4kSPS, integrated PGA and sensor bias; no internal oscillator; requires external clock for line rejection. | Targeted at multi-sensor systems needing programmable gain; lacks built-in 50/60Hz rejection-requires external filtering or firmware compensation. | Choose when system needs on-chip PGA, multiple analog inputs, or higher throughput; accept added complexity for line-noise mitigation. |
| LTC2418CGN#TRPBF | 8-channel variant of same family; identical 24-bit resolution, 2ppm INL, and 50/60Hz rejection; shares pinout and interface. | Designed for multiplexed sensor arrays (e.g., multi-point temperature or pressure monitoring) where channel count >1 is required. | Select when expanding from single-sensor to multi-sensor architecture-pin-compatible upgrade with identical performance envelope. |
Compared with ADS124S08IPWR and LTC2418CGN#TRPBF, the LTC2413CGN#TRPBF offers lowest system-level BOM count for single-channel, ultra-stable DC measurements-no PGA, no external clock, no multiplexer-making it optimal for cost- and space-constrained 6-digit DVMs and certified weighing instruments.

FAQ
What is the operating temperature range for the LTC2413CGN#TRPBF?
The LTC2413CGN#TRPBF is specified for 0°C to 70°C ambient operation (Commercial grade). This is confirmed by the "C" suffix in the part number and the Order Information table listing "LTC2413CGN#TRPBF" under "0°C to 70°C". It uses the GN (SSOP-16) package with θJA = 95°C/W.
Does the LTC2413CGN#TRPBF require external components for 50Hz/60Hz rejection?
No. The LTC2413CGN#TRPBF integrates a precision oscillator; connecting FO to GND activates internal 50Hz/60Hz simultaneous rejection without crystals, capacitors, or external clocks. The datasheet explicitly states "Internal Oscillator-No External Components Required" under Features.
Can the LTC2413CGN#TRPBF operate with a 3.3V supply and 2.5V reference?
Yes. The LTC2413CGN#TRPBF supports VCC from 2.7V to 5.5V and accepts any differential reference from 0.1V to VCC. Electrical Characteristics tables confirm operation at 2.5V REF+ with 4.5V ≤ VCC ≤ 5.5V and 2.5V ≤ REF+ ≤ VCC-fully valid at 3.3V VCC and 2.5V reference.
How does the LTC2413CGN#TRPBF achieve "no latency" in its conversion output?
The LTC2413CGN#TRPBF achieves no latency by outputting the result of the *just-completed* conversion immediately upon CS assertion-no pipeline delay or filter settling. As stated in Applications Information: "There is no latency in the conversion result. The data output corresponds to the conversion just performed."
Is the LTC2413CGN#TRPBF pin-compatible with other parts in the LTC24xx family?
Yes-the LTC2413CGN#TRPBF is pin-compatible with the LTC2410 (stated in Features) and shares the same 16-pin SSOP footprint and pin functions with the LTC2418CGN#TRPBF (8-channel variant), enabling drop-in upgrades where channel count or feature set changes are needed.
