Product details
Overview
LTC2410IGN#PBF 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#PBF datasheet, LTC2410IGN#PBF pinout, LTC2410IGN#PBF application, or LTC2410IGN#PBF equivalent, this page provides verified technical context, package mapping, real-world use scenarios, and validated alternative options for high-accuracy DC measurement systems requiring low drift and no missing codes.
Technical Context
The LTC2410IGN#PBF implements a third-order delta-sigma modulator with decimating FIR filter and on-chip auto-calibration that performs offset and full-scale correction every conversion cycle. Its internal oscillator eliminates external timing components while enabling configurable 50 Hz or 60 Hz line-frequency rejection via the FO pin.
It uses a flexible 3-wire SPI-compatible interface with CS-controlled wake-up and data output, supports external clocking up to 500 kHz, and maintains DC common-mode input rejection >140 dB across GND–VCC range - enabling direct connection to bridge sensors without signal conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 24-bit with no missing codes - guarantees monotonicity and full dynamic range utilization in precision instrumentation. |
| INL | 2 ppm of VREF - ensures ≤±0.0002% transfer curve deviation over temperature, critical for 6½-digit DVMs. |
| RMS Noise | 0.16 ppm of VREF - enables sub-microvolt resolution in low-frequency DC measurements (e.g., strain-gauge outputs). |
| Supply Current | 200 µA in conversion mode, 20 µA in sleep - allows battery-powered operation for >1 year in intermittent-sampling applications. |
| Input Range | ±0.5 × VREF differential, with independent VINCM and VREFCM from GND to VCC - supports remote sensing and floating bridge configurations. |
| Notch Rejection | ≥110 dB at 50 Hz or 60 Hz ±2% - eliminates mains interference without external filtering in industrial environments. |
| Reference Range | 0.1 V to VCC differential - permits flexible ratiometric scaling with low-voltage references or direct sensor excitation. |
Pinout & Package
Package: 16-lead plastic SSOP (GN), 0.150" wide, SO-8 footprint compatible, –40°C to +85°C operating range.
| 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 single supply; requires local 10 µF tantalum + 0.1 µF ceramic decoupling for stable conversion performance. |
| REF+ / REF– (Pins 3, 4) | Differential reference inputs | Accept 0.1V–VCC differential voltage; enable ratiometric accuracy and support remote reference sensing. |
| IN+ / IN– (Pins 5, 6) | Differential analog inputs | Support ±0.5×VREF full-scale range with GND–VCC common-mode tolerance - ideal for direct bridge digitization. |
| CS (Pin 11) | Active-low chip select | Wakes ADC from sleep, enables SDO, and triggers new conversion on falling edge - simplifies power management. |
| SDO (Pin 12) | 3-state serial data output | Outputs 32-bit conversion result MSB-first; high-impedance when CS = HIGH - enables bus sharing. |
| SCK (Pin 13) | Bidirectional serial clock | Auto-configures as input (external clock mode) or output (internal clock mode) based on power-up state. |
| FO (Pin 14) | Frequency control | Selects 50 Hz (FO = VCC), 60 Hz (FO = GND), or user-defined notch (FO = external clock) - configures digital filter null. |
Key Features
| Feature | Design Value |
|---|---|
| Single-cycle settling time | Enables true multiplexed operation without settling delay - each channel conversion is complete before next sample begins. |
| On-chip auto-calibration | Performs offset and full-scale correction every conversion - eliminates long-term drift and reduces system calibration overhead. |
| Internal oscillator | Requires zero external timing components - reduces BOM count and layout sensitivity in space-constrained designs. |
| Flexible 3-wire SPI interface | Compatible with standard microcontroller SPI peripherals - no custom driver logic required for integration. |
| DC common-mode rejection >140 dB | Rejects ground loop errors and common-mode transients - supports direct connection to unshielded industrial sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-accuracy delta-sigma ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS124S08IPWR | 24-bit, 4-kSPS, integrated PGA and burn-out current sources; requires external reference; 1.8V–3.6V supply only. | Designed for sensor signal chains with built-in excitation and gain; less suitable for direct bridge digitization without external components. | Choose for multi-channel sensor arrays needing on-chip excitation and programmable gain; avoid when using external precision references or >3.6V supplies. |
| MAX11200EEE+ | 24-bit, 10 SPS, 1.2 µA sleep current, no internal oscillator; requires external clock and reference; 2.7V–3.6V supply. | Ultra-low-power variant optimized for battery life over speed; lacks FO-pin configurability and integrated oscillator. | Choose for energy-harvesting or coin-cell applications where conversion rate ≤10 SPS is acceptable and external timing is available. |
Compared with ADS124S08IPWR and MAX11200EEE+, the LTC2410IGN#PBF uniquely combines internal oscillator, FO-pin selectable 50/60 Hz rejection, and full GND–VCC common-mode range - making it optimal for standalone, low-component-count, high-stability DC measurement nodes.

FAQ
What is the operating temperature range of the LTC2410IGN#PBF?
The LTC2410IGN#PBF is rated for –40°C to +85°C operation, as confirmed by the "IGN" suffix in the part number and the Electrical Characteristics table specifying "l" (full-range) parameters. This extended industrial temperature grade makes it suitable for deployment in harsh environments such as factory floors, outdoor instrumentation, and automotive under-hood modules where ambient temperatures exceed commercial limits.
Does the LTC2410IGN#PBF require external passive components for basic operation?
No, the LTC2410IGN#PBF requires only two external capacitors for VCC decoupling: a 10 µF tantalum in parallel with a 0.1 µF ceramic capacitor. It contains an integrated oscillator, auto-calibration circuitry, and digital filter - eliminating crystals, trimmers, or external clock sources. The FO pin configuration (VCC/GND/external) sets notch frequency without additional passives.
How does the LTC2410IGN#PBF achieve 110 dB 50/60 Hz rejection without external filters?
The LTC2410IGN#PBF achieves ≥110 dB 50/60 Hz rejection through its on-chip decimating FIR filter synchronized to its internal oscillator. When FO = VCC or FO = GND, the digital filter's first null is precisely placed at 50 Hz or 60 Hz ±2%, respectively. This architecture rejects line noise digitally - no RC networks, transformers, or active filters are needed, preserving signal integrity and reducing board area.
Can the LTC2410IGN#PBF interface directly with a microcontroller SPI peripheral?
Yes, the LTC2410IGN#PBF uses a 3-wire SPI-compatible interface (CS, SDO, SCK) with MSB-first 32-bit output. It supports both internal SCK (SCK as output) and external SCK (SCK as input) modes, auto-detected at power-up. Standard SPI master hardware can read conversion results without bit-banging or protocol translation - confirmed by compatibility statements in the datasheet and typical application schematics.
What is the significance of the "No Latency ΔΣ™" designation for the LTC2410IGN#PBF?
"No Latency ΔΣ™" means the LTC2410IGN#PBF delivers the conversion result of the *just-completed* cycle immediately upon CS assertion - with zero pipeline delay or filter settling time. Unlike conventional delta-sigma converters that buffer multiple samples, the LTC2410IGN#PBF provides true one-to-one correspondence between input sampling and output data, enabling deterministic multiplexed measurements without timing uncertainty.
