Product details
Overview
LTC2053IDD#TRPBF from Analog Devices (formerly Linear Technology) is a precision, rail-to-rail, zero-drift instrumentation amplifier with resistor-programmable gain. It features 116dB CMRR independent of gain, ≤10µV input offset voltage, <50nV/°C offset drift, 2.7V to ±5.5V supply operation, and rail-to-rail input/output swing - enabling high-accuracy signal conditioning in low-voltage, space-constrained industrial sensor interfaces.
For engineers reviewing the LTC2053IDD#TRPBF datasheet, LTC2053IDD#TRPBF pinout, LTC2053IDD#TRPBF application, or LTC2053IDD#TRPBF equivalent, key selection criteria include its sampled-data architecture, EN/CLK pin behavior (EN on LTC2053, CLK on SYNC variant), DFN-8 package thermal performance (θJA = 160°C/W), and guaranteed specifications over –40°C to +85°C.
Technical Context
The LTC2053IDD#TRPBF uses charge-balanced sampled-data techniques to convert differential input voltage into a single-ended signal, which is then amplified by an internal zero-drift op amp. Its front-end sampling frequency is fixed at 3kHz, and it requires no external clock - unlike the LTC2053-SYNC variant.
It operates with true rail-to-rail inputs and outputs, supports gain programming via two external resistors (G = 1 + R₂/R₁), and maintains CMRR ≥100dB across full common-mode range for I-grade parts. The REF pin sets output common-mode level, while RG serves as the inverting input of the internal op amp.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ±10 µV max - enables sub-16-bit DC accuracy without calibration in strain gauge or thermocouple amplifiers. |
| Offset Drift | ±50 nV/°C max - ensures stable baseline over industrial temperature range (–40°C to +85°C). |
| CMRR | 100 dB min (I-grade, VCM = 0.1V to 2.9V) - rejects power supply and EMI noise without gain-dependent degradation. |
| Supply Range | 2.7V single-supply or ±5.5V dual-supply - supports battery-powered sensors and legacy industrial rails. |
| Output Swing | Rail-to-rail (20 mV from rail, RL = 2kΩ) - maximizes dynamic range in low-voltage ADC interfacing. |
| Supply Current | 0.75–1.1 mA - enables always-on precision sensing in energy-conscious systems. |
| Shutdown Current | 10 µA (VEN ≥ 2.5V) - allows low-power duty-cycled operation in portable instrumentation. |
Pinout & Package
Package: 8-lead (3mm × 3mm) plastic DFN (DD package), underside metal pad internally connected to V–; θJA = 160°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (EN) | Active-low enable | Drives device into 10 µA shutdown when pulled high (>2.5V); default-enabled when floating or grounded. |
| 2 (–IN) | Inverting input | Differential input terminal; rail-to-rail common-mode range; sensitive to source resistance mismatch. |
| 3 (+IN) | Noninverting input | Differential input terminal; matched impedance path required for optimal CMRR and offset performance. |
| 4 (V–) | Negative supply | Reference for internal sampling circuitry and output swing; underside thermal pad tied to this node. |
| 5 (REF) | Output reference | Sets output common-mode voltage; must be within ±5.5V of input pins to avoid damage. |
| 6 (RG) | Internal op amp inverting input | Connects to external feedback resistor network; defines DC gain (G = 1 + R₂/R₁). |
| 7 (OUT) | Amplifier output | Single-ended, rail-to-rail output; drives 2kΩ load with <20 mV headroom. |
| 8 (V+) | Positive supply | Supports up to 11V total supply (V+ to V–); bypass with 0.1 µF ceramic capacitor directly between Pins 4 and 8. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | Eliminates 1/f noise and long-term drift - critical for DC-coupled medical and weigh-scale applications. |
| Resistor-programmable gain | Two external resistors set precise gain (1 to >1000) without trimming or digital interface overhead. |
| Rail-to-rail I/O | Enables full utilization of 3V or ±5V supplies - preserves SNR when driving SAR or delta-sigma ADCs. |
| Sampled-data front end | 3 kHz internal sampling eliminates need for external clock; immune to RF rectification in noisy environments. |
| Guaranteed specs over –40°C to +85°C | Validated performance across full industrial temperature range - no derating required for embedded deployment. |
Applications
| Thermocouple Amplifiers | Electronic Scales |
|---|---|

| Medical Instrumentation | Strain Gauge Amplifiers |
Use Scenario: Front-end amplification of biopotential signals (ECG, EMG) in portable patient monitors.

Equivalent & Alternatives
The following parts are listed as comparable options for similar instrumentation amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8421ARMZ | Fixed-gain options (10, 100, 1000); higher bandwidth (12 MHz); no shutdown mode; MSOP-8 only. | Better for high-speed, fixed-gain DAQ; unsuitable where adjustable gain or low-power shutdown is required. | Select AD8421ARMZ when system requires >100 kHz bandwidth and gain is fixed; LTC2053IDD#TRPBF preferred for DC-precision, programmable gain, and shutdown. |
| INA333AIDRGT | Auto-zero architecture; lower quiescent current (50 µA); smaller offset drift (0.1 µV/°C); same DFN-8 footprint. | Superior for ultra-low-power, battery-operated sensors; lacks rail-to-rail output swing (min 100 mV from rail). | Choose INA333AIDRGT for <100 µA systems needing lowest drift; LTC2053IDD#TRPBF retains advantage in rail-to-rail output and higher CMRR at G=1. |
Compared with AD8421ARMZ and INA333AIDRGT, the LTC2053IDD#TRPBF uniquely combines guaranteed 10 µV offset, 116 dB CMRR independent of gain, rail-to-rail output, and shutdown capability in a thermally enhanced DFN package - making it optimal for industrial sensor nodes requiring DC accuracy, flexibility, and robustness.

FAQ
What is the operating temperature range for the LTC2053IDD#TRPBF?
The LTC2053IDD#TRPBF is rated for –40°C to +85°C (I-grade). This specification is guaranteed per the datasheet's Electrical Characteristics table and Absolute Maximum Ratings section, and applies to all electrical parameters including offset voltage, CMRR, and supply current across the full range.
Does the LTC2053IDD#TRPBF require an external clock?
No - the LTC2053IDD#TRPBF uses an internal 3 kHz sampling clock and has no CLK pin. Pin 1 is EN (active-low enable). Only the LTC2053-SYNC variants feature a CLK input; the LTC2053IDD#TRPBF is the non-synchronized version.
What is the function of the REF pin on the LTC2053IDD#TRPBF?
The REF pin (Pin 5) sets the output common-mode voltage. The output swings around this reference level - e.g., if REF = 1.25 V, OUT ranges from ~1.25 V – 2.7 V to ~1.25 V + 2.7 V (depending on supply). It must remain within ±5.5 V of both input pins to prevent damage.
Can the LTC2053IDD#TRPBF operate from a single 3V supply?
Yes - the LTC2053IDD#TRPBF supports single-supply operation down to 2.7 V. With V+ = 3 V and V– = 0 V, it delivers rail-to-rail input and output swing, and all key specs (offset, CMRR, noise) are characterized at 3 V in the datasheet.
How is gain programmed on the LTC2053IDD#TRPBF?
Gain is set by two external resistors: G = 1 + R₂/R₁. R₁ connects between +IN and RG (Pin 3 → Pin 6); R₂ connects between RG and OUT (Pin 6 → Pin 7). No internal resistors are used - full flexibility and precision depend on external component selection and layout matching.
