Product details
Overview
LTC2430IGN#TRPBF from Analog Devices (formerly Linear Technology) is a 20-bit micropower delta-sigma analog-to-digital converter with differential input and reference, integrated oscillator, 3ppm INL, 0.56ppm RMS noise, and single-cycle settling-designed for high-accuracy sensor digitization in weight scales, strain gauge transducers, and industrial process control systems.
For engineers reviewing the LTC2430IGN#TRPBF datasheet, LTC2430IGN#TRPBF pinout, LTC2430IGN#TRPBF application, or LTC2430IGN#TRPBF equivalent, this page delivers verified specifications including 2.7V–5.5V supply operation, 110dB 50/60Hz notch rejection, GND-to-VCC common-mode input/reference range, 200µA conversion current, and SPI/MICROWIRE-compatible 3-wire interface.
Technical Context
The LTC2430IGN#TRPBF implements a decimating FIR filter with internal oscillator-based clocking, enabling precise 50Hz or 60Hz line-frequency rejection without external components. Its auto-calibration architecture performs offset and full-scale correction every conversion cycle, ensuring long-term stability across temperature and supply voltage variations.
It operates in three distinct states-conversion, sleep, and data output-with CS-controlled wake-up and SCK-gated serial data transfer. The FO pin selects internal 50Hz (FO = VCC) or 60Hz (FO = GND) rejection, or enables user-defined rejection via external oscillator at fEOSC/2560.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 20-bit, no missing codes-guarantees monotonicity and full code coverage over full input range. |
| INL | 3ppm of VREF (max)-enables ±0.0003% full-scale accuracy for precision metrology applications. |
| RMS Noise | 0.56ppm of VREF (typ)-supports 20.8 ENOB at 7.5Hz output rate with 5V reference. |
| Supply Current | 200µA in conversion mode, 4µA in autosleep-enables battery-powered portable instrumentation. |
| Common-Mode Range | GND to VCC for both inputs and reference-allows direct interfacing with unbuffered sensors and ratiometric configurations. |
| Line Rejection | ≥110dB at 50Hz or 60Hz ±2%-eliminates mains interference without external filtering or synchronous sampling. |
| Settling Time | Single-cycle-no latency or filter delay; each output corresponds precisely to its input sample, enabling true multiplexed multi-channel measurement. |
Pinout & Package
Package: 10-lead MSOP (GN), RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Positive supply input | 2.7V–5.5V operation; requires local 10µF tantalum + 0.1µF ceramic bypass to GND. |
| REF+ / REF– (Pins 2, 3) | Differential reference inputs | Accept 0.1V–VCC differential voltage; common-mode range spans GND to VCC for flexible ratiometric sensing. |
| IN+ / IN– (Pins 4, 5) | Differential analog inputs | Support –0.5VREF to +0.5VREF differential range; absolute input range extends to GND–0.3V / VCC+0.3V. |
| GND (Pin 6) | Analog/digital ground | Low-impedance connection point for decoupling and signal return; must be tied to system ground plane. |
| CS (Pin 7) | Active-low chip select | Wakes device from autosleep (4µA); enables SDO output and initiates data transfer; rising edge aborts transfer and starts new conversion. |
| FO (Pin 10) | Frequency control input | Selects internal 50Hz (FO = VCC) or 60Hz (FO = GND) notch; accepts external clock for custom rejection frequency at fEOSC/2560. |
| SDO (Pin 8) | Three-state serial data output | Outputs 24-bit conversion result on falling SCK edge; high-Z when CS = HIGH; indicates conversion status during sleep/conversion. |
| SCK (Pin 9) | Bidirectional serial clock | Functions as output (internal clock mode) or input (external clock mode); mode auto-selected at power-up or CS falling edge. |
Key Features
| Feature | Design Value |
|---|---|
| No-latency delta-sigma architecture | Delivers one accurate 20-bit result per conversion cycle-no filter settling delay or redundant samples required for multiplexed inputs. |
| Per-conversion auto-calibration | Eliminates drift-related errors by correcting offset and full-scale in every cycle-ensures stability over time, temperature, and supply variation. |
| Configurable 50/60Hz rejection | Hardware-selectable notch via FO pin-achieves ≥110dB rejection without software configuration or external timing components. |
| True differential input & reference | Independent GND-to-VCC common-mode ranges for IN+/IN– and REF+/REF–-enables remote sensing, floating bridges, and wide-range sensor interfaces. |
| Ultra-low-power autosleep mode | 4µA quiescent current with indefinite result retention-ideal for intermittent-read applications like portable DVMs and battery-operated weigh scales. |
Applications
| Weight Scales | Strain Gauge Transducers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-accuracy, low-power ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2410CGN#PBF | 24-bit resolution, same 10-lead MSOP package, but higher 350µA conversion current and no FO pin for 50/60Hz selection. | Targeted at ultra-high-resolution applications where 24-bit depth outweighs power and line-rejection flexibility. | Choose LTC2410CGN#PBF only if 24-bit resolution is mandatory and 50/60Hz rejection can be handled externally or is unnecessary. |
| ADS124S08IPWR | Texas Instruments 24-bit delta-sigma ADC with integrated PGA, reference, and 50/60Hz rejection-but requires external clock or configuration register writes to enable notch. | Designed for sensor signal chains needing programmable gain and on-chip excitation, not direct ratiometric digitization. | Choose ADS124S08IPWR when PGA, IDACs, or multiple sensor inputs are needed; LTC2430IGN#TRPBF offers simpler, lower-power, hardware-configured operation. |
Compared with LTC2410CGN#PBF and ADS124S08IPWR, the LTC2430IGN#TRPBF uniquely combines 20-bit precision, hardware-selectable 50/60Hz rejection, 4µA autosleep, and true GND-to-VCC differential input/reference-all in a 10-pin MSOP-making it optimal for cost-sensitive, low-power, line-immune sensor digitization without firmware overhead.

FAQ
What is the operating temperature range for the LTC2430IGN#TRPBF?
The LTC2430IGN#TRPBF is specified for operation from –40°C to +85°C (Industrial grade). This range is confirmed in the Absolute Maximum Ratings table and Electrical Characteristics section of the official datasheet, where parameters such as INL, noise, and supply current are guaranteed over this full temperature span.
Does the LTC2430IGN#TRPBF require external passive components for its internal oscillator?
No, the LTC2430IGN#TRPBF requires no external passive components for its internal oscillator. As stated in the Features and Description sections, the internal oscillator needs no external frequency-setting components-enabling immediate 50Hz or 60Hz notch filtering upon connecting FO to VCC or GND.
Can the LTC2430IGN#TRPBF accept a 0.1V reference voltage?
Yes, the LTC2430IGN#TRPBF supports differential reference voltages from 0.1V to VCC, as explicitly specified in the Electrical Characteristics table under "VREF Reference Differential Voltage Range" and confirmed in the Applications Information section on Reference Voltage Range.
How does the FO pin affect conversion time in the LTC2430IGN#TRPBF?
The FO pin directly sets conversion time: FO = GND yields 130.86–136.20ms (60Hz mode); FO = VCC yields 157.03–163.44ms (50Hz mode). These values are measured and guaranteed in the Timing Characteristics table, reflecting the underlying oscillator frequency difference (153.6kHz vs. 128kHz).
Is the LTC2430IGN#TRPBF pin-compatible with the LTC2431IMS?
No-the LTC2430IGN#TRPBF (10-pin MSOP) and LTC2431IMS (16-pin SSOP) have different pin counts, layouts, and grounding schemes. The datasheet explicitly notes separate package drawings and pin functions; the LTC2430IGN#TRPBF has only one GND pin (Pin 6), while the LTC2431IMS has seven GND pins, confirming non-interchangeability.
