Product details
Overview
LTC2483IDD#TRPBF from Analog Devices (formerly Linear Technology) is a 16-bit plus sign delta-sigma analog-to-digital converter with patented Easy Drive input current cancellation, I²C interface, and integrated oscillator. It delivers 600 nVRMS noise independent of reference voltage, ±2 ppm INL, and simultaneous 50 Hz/60 Hz rejection - enabling direct digitization of rail-to-rail, high-impedance sensor signals in industrial instrumentation and precision weighing systems.
For engineers reviewing the LTC2483IDD#TRPBF datasheet, LTC2483IDD#TRPBF pinout, LTC2483IDD#TRPBF application, or LTC2483IDD#TRPBF equivalent, key selection considerations include its zero differential input current architecture, GND-to-VCC common-mode input range, internal oscillator eliminating external crystals, and six configurable I²C addresses for multi-device bus operation.
Technical Context
The LTC2483IDD#TRPBF implements a third-order delta-sigma modulator with transparent auto-calibration of offset and full-scale errors across temperature and time. Its Easy Drive sampling scheme cancels dynamic differential input current via passive network timing, enabling direct connection to sensors with source impedances up to 100 kΩ without signal degradation.
It uses an on-chip trimmed oscillator (no external crystal required) to achieve 87 dB simultaneous 50 Hz/60 Hz line-frequency rejection. The 24-bit output format includes sign and MSB bits for overrange/underrange detection, and conversion settles in a single digital filter cycle - delivering true no-latency performance for real-time monitoring applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit plus sign, no missing codes - guarantees monotonicity and unambiguous code mapping across full input range. |
| INL Error | ±2 ppm (0.25 LSB) - ensures sub-LSB linearity for high-accuracy weight scale and strain gauge measurements. |
| Output Noise | 0.6 µVRMS, independent of VREF - enables stable 16-bit accuracy even with low reference voltages (down to 100 mV). |
| Input Common-Mode Range | GND to VCC - supports direct digitization of sensors referenced to ground or supply without level-shifting circuitry. |
| I²C Interface | Standard/fast mode (up to 400 kHz), 6 address options - simplifies multi-node sensor networks with minimal bus contention. |
| Supply Voltage | 2.7 V to 5.5 V - compatible with both 3.3 V and 5 V industrial control rails. |
| Operating Temp | –40°C to +85°C - qualified for extended industrial environments including factory automation and process control. |
Pinout & Package
Package: 10-lead (3 mm × 3 mm) plastic DFN with exposed pad (Pin 11 = GND, must be soldered to PCB). Thermal resistance θJA = 43°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| REF+ / REF– | Differential reference inputs | Accept reference voltage from 0.1 V to VCC; enable flexible scaling without external buffers. |
| IN+ / IN– | Differential analog inputs | Rail-to-rail common-mode range (GND to VCC) with zero differential input current - directly interface thermocouples, bridge sensors, or high-Z pH electrodes. |
| VCC / GND | Power supply and ground | Require local bypassing (1 µF tantalum || 0.1 µF ceramic); exposed pad must be connected to GND for thermal and electrical integrity. |
| SCL / SDA | I²C clock and bidirectional data | Open-drain SDA requires external pull-up; supports standard/fast mode up to 400 kHz with built-in spike suppression. |
| CA0/F0 / CA1 | I²C address configuration / external clock input | Two 3-state pins configure one of six slave addresses; CA0/F0 accepts external oscillator (10–4000 kHz) to shift rejection null frequency. |
Key Features
| Feature | Design Value |
|---|---|
| Easy Drive™ Input Current Cancellation | Eliminates differential input current errors without on-chip buffers - preserves DC accuracy with RC filters or >100 kΩ sensor sources. |
| No-Latency Digital Filter | Single-cycle settling enables immediate read-after-convert sequencing - critical for responsive closed-loop control feedback. |
| Simultaneous 50 Hz/60 Hz Rejection | 87 dB rejection at both frequencies using internal oscillator - removes mains interference without external notch filters or software averaging. |
| Auto-Calibration Architecture | Continuous, transparent offset and full-scale calibration - maintains absolute accuracy over temperature and time without user intervention. |
| Low-Power Sleep Mode | 1 µA typical quiescent current - extends battery life in portable DVMs and wireless sensor nodes between conversions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision, low-power delta-sigma ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS124S08IPW | 24-bit resolution, integrated PGA and burnout current sources; requires external reference; no built-in oscillator. | Better suited for multi-channel sensor arrays with programmable gain; lacks Easy Drive's zero-differential-current advantage for ultra-high-Z sources. | Select when higher resolution and channel multiplexing are prioritized over minimal external components and direct high-Z sensor interfacing. |
| MAX11200EEE+ | 24-bit, 10 µVOS offset, SPI interface only; no I²C support; requires external clock or crystal. | Optimized for ultra-low-noise laboratory instruments; incompatible with I²C-based microcontroller platforms without protocol translation. | Choose for maximum DC precision in benchtop equipment where SPI infrastructure exists and board space allows external timing components. |
Compared with ADS124S08IPW and MAX11200EEE+, the LTC2483IDD#TRPBF uniquely combines I²C compatibility, integrated oscillator, zero-differential-input-current operation, and guaranteed 16-bit no-missing-codes performance in a 3 mm × 3 mm DFN - making it optimal for space-constrained, low-component-count industrial sensor nodes requiring robustness and ease of integration.

FAQ
What is the operating temperature range of the LTC2483IDD#TRPBF?
The LTC2483IDD#TRPBF is rated for –40°C to +85°C, making it suitable for industrial environments such as factory automation, outdoor instrumentation, and process control systems. This grade ('I') exceeds the commercial-grade 'C' version (0°C to 70°C) and is validated across the full range for parameters including INL, offset drift, and noise performance.
Does the LTC2483IDD#TRPBF require an external crystal or oscillator?
No, the LTC2483IDD#TRPBF includes an on-chip trimmed oscillator, eliminating the need for external timing components. It achieves 87 dB simultaneous 50 Hz/60 Hz rejection using this internal clock. An external oscillator (10–4000 kHz) may be applied to CA0/F0 only if custom rejection frequency placement is required - but it is not necessary for standard operation.
How does Easy Drive technology benefit sensor interfacing in the LTC2483IDD#TRPBF?
Easy Drive technology in the LTC2483IDD#TRPBF cancels differential input current through a patented passive sampling scheme, enabling direct connection to high-impedance sensors (e.g., thermocouples, RTDs, piezoresistive bridges) without external op-amps or buffers. This preserves DC accuracy, reduces component count, and avoids errors introduced by input bias current in traditional amplifier-based front ends.
What is the I²C address configuration capability of the LTC2483IDD#TRPBF?
The LTC2483IDD#TRPBF supports six unique I²C slave addresses via two 3-state address pins (CA1 and CA0/F0), configured as LOW, HIGH, or floating. This allows up to six LTC2483IDD#TRPBF devices on a single I²C bus without address conflicts - ideal for multi-sensor nodes in industrial monitoring and test equipment.
Can the LTC2483IDD#TRPBF operate with a 100 mV reference voltage?
Yes, the LTC2483IDD#TRPBF supports reference voltages as low as 100 mV (0.1 V) across the full operating temperature range. Its 600 nVRMS output noise is independent of VREF, so 16-bit effective resolution is maintained even at low reference levels - enabling high-gain, low-voltage sensor interfaces such as millivolt-output load cells without additional amplification.
