Product details
Overview
LT1213ACN8#PBF from Analog Devices (formerly Linear Technology) is a dual precision operational amplifier optimized for single-supply operation with 28MHz gain-bandwidth, 12V/µs slew rate, and ≤150µV input offset voltage at 25°C. It operates from 2.5V to 36V total supply, delivers ±30mA output current, and supports rail-to-rail input (including ground) and near-rail output swing - ideal for 12-bit DAC current-to-voltage conversion and battery-powered instrumentation.
For engineers reviewing the LT1213ACN8#PBF datasheet, LT1213ACN8#PBF pinout, LT1213ACN8#PBF application, or LT1213ACN8#PBF equivalent, key selection criteria include guaranteed 150µV max VOS over temperature, 3µV/°C drift in N8 package, 10nV/√Hz input noise, and compatibility with 3.3V/5V/±15V supplies without performance degradation.
Technical Context
The LT1213ACN8#PBF uses a proprietary bipolar input stage enabling wide common-mode range (down to V–) and high DC precision while maintaining high-speed performance. Its internal compensation ensures stability with capacitive loads up to 100pF and unity-gain bandwidth of 26MHz at 5V supply.
It features matched dual amplifiers sharing thermal and layout symmetry, delivering >128dB channel separation at 1kHz and low crosstalk in multi-channel signal conditioning. The device maintains 45° phase margin across –40°C to 85°C and supports fast settling (500ns to 0.01% for 2V step) without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 28MHz typical - enables stable closed-loop operation up to 10MHz with gain ≥2.8. |
| Slew Rate | 12V/µs typical - supports clean 10Vpp signals up to ~1.1MHz without slewing distortion. |
| Input Offset Voltage | ≤150µV at 25°C - eliminates trimming in 12-bit systems (≤0.45LSB error at 2.5V full-scale). |
| Input Offset Drift | ≤3µV/°C (N8 package) - ensures <0.5mV total VOS shift over –40°C to 85°C operating range. |
| Supply Range | 2.5V to 36V total - supports single 3.3V/5V or split ±15V rails without redesign. |
| Output Drive | ±30mA minimum - directly drives 50Ω loads or 100Ω cables without external buffers. |
| Input Noise | 10nV/√Hz at 1kHz - preserves SNR in low-level sensor amplification (e.g., photodiode transimpedance). |
Pinout & Package
LT1213ACN8#PBF is housed in an 8-lead plastic DIP (N8) package with 0.3-inch body width and through-hole mounting. Thermal resistance θJA = 100°C/W.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - capable of sourcing/sinking 30mA while swinging within 4mV of V– and 1.25V of V+. |
| 2 | –IN A | Inverting input of Amplifier A - high-impedance node (<200nA bias current) for precision feedback networks. |
| 3 | +IN A | Non-inverting input of Amplifier A - accepts common-mode voltages from V– to (V+ – 1.5V) at 5V supply. |
| 4 | V– | Negative supply rail - must be bypassed with 0.01µF capacitor within 25mm of pin for stability. |
| 5 | V+ | Positive supply rail - requires local 0.01µF + 4.7µF bypassing when driving heavy loads. |
| 6 | OUT B | Amplifier B output - electrically isolated from OUT A; shares same drive capability and voltage swing limits. |
| 7 | –IN B | Inverting input of Amplifier B - independent of Amplifier A; enables dual-channel signal processing on one IC. |
| 8 | +IN B | Non-inverting input of Amplifier B - identical electrical characteristics to +IN A; supports matched dual configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Operates with inputs down to V– (ground in single-supply), eliminating level-shifting circuitry in sensor interfaces. |
| Low input offset drift | 3µV/°C max in N8 package - reduces calibration frequency in industrial temperature-sensing front-ends. |
| High PSRR and CMRR | ≥90dB PSRR and ≥88dB CMRR over –40°C to 85°C - rejects power supply ripple and common-mode interference in noisy environments. |
| Fast settling time | 500ns to 0.01% for 2V step - meets timing requirements in high-throughput data acquisition systems. |
| Single-supply optimized architecture | Guaranteed functionality at 2.5V total supply - enables direct integration into ultra-low-power portable medical devices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1213CN8#PBF | Higher max VOS (275µV vs. 150µV) and drift (6µV/°C vs. 3µV/°C); otherwise identical pinout, specs, and package. | Suitable for cost-sensitive designs where 12-bit accuracy is not required; less suitable for 16-bit systems. | Select LT1213CN8#PBF only if VOS budget allows ≥275µV error at 25°C and system calibration compensates for higher drift. |
| OP27GPZ | Lower noise (3.5nV/√Hz), higher GBW (8MHz), but no rail-to-rail input and requires ±15V min supply; SO-8 package only. | Preferred in legacy ±15V lab equipment where ultra-low noise dominates; incompatible with 3.3V single-supply systems. | Choose OP27GPZ only for high-precision analog test gear with fixed ±15V rails and noise-critical signal paths. |
Compared with LT1213CN8#PBF, LT1213ACN8#PBF delivers tighter VOS and drift for untrimmed 12-bit systems, while OP27GPZ offers superior noise performance in high-voltage, narrow-bandwidth applications - neither is pin-compatible with LT1213ACN8#PBF in single-supply configurations.

FAQ
What is the maximum operating temperature range for LT1213ACN8#PBF?
The LT1213ACN8#PBF is rated for operation from –40°C to +85°C ambient temperature. This grade is specified and tested across that full range, with all electrical parameters guaranteed per the datasheet tables under those conditions. The N8 package has a maximum junction temperature of 150°C, supported by its 100°C/W thermal resistance.
Does LT1213ACN8#PBF support true rail-to-rail output swing?
The LT1213ACN8#PBF does not achieve full rail-to-rail output swing. Its output swings to within 4mV of V– (enabling ground-referenced operation in single-supply setups) but only to within ~1.25V of V+ when sourcing 30mA. At light loads, it reaches within ~70mV of V+. This asymmetry is inherent to its bipolar output stage and is fully characterized in the datasheet's output swing tables.
Can LT1213ACN8#PBF operate from a 3.3V single supply?
Yes, LT1213ACN8#PBF is fully specified and guaranteed for 3.3V single-supply operation. Key parameters-including input offset voltage (≤150µV), gain-bandwidth (26MHz), and output swing (2.6Vpp into high-Z load)-are explicitly tested and published for VS = 3.3V. Its minimum supply requirement of 2.5V ensures robust startup and regulation even with battery droop.
What is the input bias current specification for LT1213ACN8#PBF?
The LT1213ACN8#PBF has a maximum input bias current of 200nA at 25°C, with typical values around 100nA. Over the full –40°C to +85°C range, bias current remains below 250nA. This low value enables use with high-value feedback resistors (e.g., 1MΩ) in precision transimpedance and filtering applications without significant DC error.
Is LT1213ACN8#PBF pin-compatible with other LT1213 variants?
Yes, LT1213ACN8#PBF is pin-compatible with all LT1213 variants in the N8 (8-lead plastic DIP) package, including LT1213CN8#PBF and LT1213MJ8. All share identical pinout, footprint, and mechanical dimensions. Electrical differences (e.g., VOS, drift, temperature grade) do not affect physical or functional interoperability on the PCB.
