Product details
Overview
LTC2463IMS#PBF from Analog Devices (formerly Linear Technology) is a 16-bit differential ΔΣ analog-to-digital converter with integrated 1.25V precision reference, I²C interface, and ultra-low 200nA sleep current. It operates from 2.7V to 5.5V, delivers 60 conversions per second, and features ±2 LSB offset error (typ), 0.01% gain error (typ), and 2ppm/°C reference drift (I-grade). It is used in high-accuracy sensor signal digitization for industrial monitoring systems.
For engineers reviewing the LTC2463IMS#PBF datasheet, LTC2463IMS#PBF pinout, LTC2463IMS#PBF application, or LTC2463IMS#PBF equivalent, key selection criteria include its differential input architecture, guaranteed no-missing-codes performance, internal oscillator eliminating external timing components, and MSOP-12 package compatibility with space-constrained embedded measurement nodes.
Technical Context
The LTC2463IMS#PBF implements a delta-sigma conversion architecture with proprietary input sampling that reduces average input current to 50nA-enabling direct RC filter interfacing without significant error. Its integrated 1.25V reference achieves ±2 ppm/°C drift over –40°C to +85°C and supports full-scale differential input range of ±1.25V.
It uses a fixed 2-wire I²C interface with two selectable slave addresses (0010100b or 1010100b via A0 pin) plus global address synchronization capability. Conversion settling is single-cycle with no latency, and continuous internal offset/full-scale calibration runs transparently every conversion cycle.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit, no missing codes-guarantees monotonicity and full dynamic range utilization in precision measurement. |
| Input Type | Differential-rejects common-mode noise and enables true bipolar signal acquisition relative to REF–. |
| Reference Voltage | 1.25V ±3mV (1.247V–1.253V)-sets full-scale input range; stable over temperature and supply voltage variation. |
| Conversion Rate | 60 conversions/second-supports real-time monitoring of slow-varying physical parameters (e.g., temperature, pressure). |
| Sleep Current | 200nA-enables multi-year battery operation in remote sensor nodes when idle between measurements. |
| Offset Error | ±2 LSB (typ)-translates to <±76µV error at 1.25V full scale, critical for sub-millivolt-level transducer signals. |
| Gain Error | ±0.01% FS (typ)-ensures accurate scaling across operating temperature without periodic recalibration. |
Pinout & Package
Package: 12-lead plastic MSOP (3mm × 4.9mm), exposed pad grounded, rated for –40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| REFOUT (1) | Reference output | Nominally 1.25V reference source; must be decoupled with ≤0.1µF capacitor to GND for stability. |
| COMP (2) | Reference compensation | Requires 0.1µF capacitor to GND to stabilize internal reference; value must match or exceed REFOUT capacitor. |
| A0 (3) | I²C address select | Logic level sets slave address: GND → 0010100b, VCC → 1010100b-enables dual-device bus configuration. |
| GND (4, 7, 11) | Ground return | Three dedicated ground pins minimize ground bounce; exposed pad (Pin 13 in DFN variant) is not present in MSOP package. |
| SCL (5) | I²C clock input | Slave-only interface; accepts external clock up to 400kHz; rising edge clocks data into device, falling edge clocks data out. |
| SDA (6) | I²C bidirectional data | Open-drain output requiring external pull-up; outputs 16-bit conversion result MSB-first on falling SCL edges. |
| REF– (8) | Negative reference input | Sets zero-input point; tied directly to system ground or sensor low-side reference for accurate differential measurement. |
| IN+ (9) | Positive differential input | Accepts input up to VREF above REF–; supports signals slightly below ground (down to –8 LSB) due to proprietary sampling scheme. |
| IN– (10) | Negative differential input | Accepts input down to VREF below REF–; enables true bipolar measurement with common-mode rejection. |
| VCC (12) | Supply voltage | 2.7V–5.5V operation; requires local 10µF + 0.1µF parallel bypassing for low-noise ADC performance. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 1.25V reference | 2ppm/°C max drift (I-grade) and 0.1% initial accuracy eliminate need for external precision reference and reduce BOM count. |
| Proprietary input sampling | 50nA average input current enables direct connection to RC filters (e.g., 1kΩ + 0.1µF) with <1 LSB added error. |
| Single-cycle conversion settling | No latency or filter delay-ideal for multiplexed sensor arrays where each channel must be sampled rapidly and deterministically. |
| Continuous internal calibration | Automatic offset and full-scale correction every conversion ensures long-term accuracy without user intervention or firmware overhead. |
| Ultra-low sleep current | 200nA shutdown state allows energy harvesting or coin-cell-powered deployments with years of operational life. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision delta-sigma ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS1115IDGSR | 4-channel, 16-bit, PGA-integrated; 2ppm/°C ref; 860µA active current; no internal oscillator-requires external clock or MCU timing. | Supports multiplexed 4-input sensing but lacks differential-only simplicity and ultra-low sleep current (0.15µA vs 0.2µA). | Choose ADS1115IDGSR when multi-channel scanning or programmable gain is needed; LTC2463IMS#PBF preferred for lowest power and minimal external components. |
| MAX11613AUT+T | 8-bit, 100ksps SAR ADC; no integrated reference; 1.2µA typical supply current; SPI interface only. | Higher speed but lower resolution and no internal reference-requires external 1.25V source and additional decoupling. | Choose MAX11613AUT+T for cost-sensitive, high-throughput applications where 8-bit resolution suffices; LTC2463IMS#PBF selected for metrology-grade accuracy and self-contained operation. |
Compared with ADS1115IDGSR and MAX11613AUT+T, the LTC2463IMS#PBF uniquely combines integrated 1.25V reference, 200nA sleep current, and differential-only architecture-making it optimal for ultra-low-power, high-accuracy, single-sensor measurement nodes where component count and long-term stability are critical.

FAQ
What is the operating temperature range for the LTC2463IMS#PBF?
The LTC2463IMS#PBF is specified for operation from –40°C to +85°C (I-grade). This rating is confirmed in the Absolute Maximum Ratings table and Electrical Characteristics section of the official datasheet, and applies to both the MSOP-12 and DFN package variants bearing the "I" suffix. The "IMS" part number explicitly denotes the MSOP package with industrial temperature range.
Does the LTC2463IMS#PBF require an external crystal or clock source?
No, the LTC2463IMS#PBF does not require an external crystal or clock source. It integrates a precision internal oscillator, enabling fully autonomous operation with no external timing components. This is explicitly stated in the FEATURES list ("Internal Oscillator-No External Components Required") and confirmed in the APPLICATIONS INFORMATION section under "Converter Operation Cycle" and "Ease of Use".
How does the LTC2463IMS#PBF handle input signals below ground potential?
The LTC2463IMS#PBF supports input voltages slightly below ground on IN+ or IN– due to its proprietary sampling architecture. As documented in Figure 3 and the "Input Voltage Range (LTC2463)" section, it can digitize signals up to ~8 LSBs (≈305µV) below GND when the differential input remains within ±VREF. This enables direct measurement of signals like thermocouples or biased transducers without level-shifting circuitry.
What is the I²C address configuration for the LTC2463IMS#PBF?
The LTC2463IMS#PBF supports two I²C slave addresses determined by the logic level on the A0 pin: 0010100b (0x24) when A0 = GND, and 1010100b (0x54) when A0 = VCC. Both addresses are listed in the PIN FUNCTIONS section. Additionally, it responds to the global address 1110111b (0x77) for synchronized conversion start across multiple devices on the same bus.
Can the internal reference of the LTC2463IMS#PBF be powered down independently?
Yes, the internal reference of the LTC2463IMS#PBF can be powered down independently via the SLP (sleep) bit in the 4-bit data input word. When SLP = 1, the reference powers down after the next conversion completes and remains off until a valid I²C address is acknowledged. Reference startup time is 12ms with standard 0.1µF capacitors on REFOUT and COMP pins, as detailed in the "Data Input Format" subsection.
