Product details
Overview
LT1499HS#PBF from Analog Devices (formerly Linear Technology) is a quad rail-to-rail input and output precision operational amplifier optimized for single- and dual-supply signal conditioning in high-accuracy data acquisition systems. It delivers 10MHz gain-bandwidth, 6V/μs slew rate, 475μV max input offset voltage, 110dB PSRR, and guaranteed <1LSB error when buffering 12-bit ADCs at 3V supply.
For engineers reviewing the LT1499HS#PBF datasheet, LT1499HS#PBF pinout, LT1499HS#PBF application, or LT1499HS#PBF equivalent, this page provides verified electrical specifications, thermal-grade package details (–40°C to 125°C), rail-to-rail dynamic range validation, and real-world op amp selection guidance for low-voltage precision analog front-ends.
Technical Context
The LT1499HS#PBF employs a patented dual-input-stage trimming architecture-separately calibrating NPN and PNP input stages at V– and V+-to achieve superior common-mode rejection (>93dB) across full rail-to-rail input range. This eliminates typical rail-to-rail op amp performance degradation near supply rails.
It maintains stability driving capacitive loads up to 10,000pF without external compensation and supports wide supply operation from 2.2V single-ended to ±15V dual supplies. Its C-Load™ design ensures predictable phase margin and settling behavior under heavy capacitive loading conditions typical in sensor interface and DAC output buffering.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP4177ARUZ | Lower GBW (1.3MHz), lower slew rate (0.7V/μs), but superior offset drift (0.3μV/°C) and lower noise (7.9nV/√Hz). | Better suited for DC-coupled precision instrumentation (e.g., weigh scales) where bandwidth <100kHz suffices. | Select OP4177ARUZ when ultra-low drift dominates over speed; avoid for >100kHz active filtering or fast ADC buffering. |
| TLV2464CDR | Higher quiescent current (820μA/amp vs 1.7mA), lower PSRR (90dB), no guaranteed 12-bit ADC error spec, but wider temp range (–40°C to 125°C). | Cost-optimized for consumer-grade portable devices where 10-bit accuracy is sufficient and supply noise is low. | Select TLV2464CDR only for non-critical signal paths; cannot replace LT1499HS#PBF in automotive or industrial 12-bit+ designs. |
Compared with OP4177ARUZ and TLV2464CDR, the LT1499HS#PBF uniquely balances 10MHz bandwidth, rail-to-rail operation, and guaranteed 12-bit ADC error performance across –40°C to 125°C - making it irreplaceable in high-speed, high-accuracy, thermally demanding applications.

FAQ
What is the maximum capacitive load the LT1499HS#PBF can drive without oscillation?
The LT1499HS#PBF is specified to remain stable driving capacitive loads up to 10,000pF with no external compensation required. This capability is enabled by its proprietary C-Load™ architecture, which modifies internal compensation based on load conditions. At 10,000pF, overshoot remains below 20% with 10% settling time under 1μs for a 2V step, as verified in the LT1499HS#PBF datasheet Figure 19.
Does the LT1499HS#PBF meet the 12-bit ADC buffer specification at its full –40°C to 125°C operating range?
Yes - the LT1499HS#PBF is the H-grade variant explicitly qualified for –40°C to 125°C operation and guaranteed to add less than 1LSB of error when used as a unity-gain buffer driving 12-bit ADCs at 3V supply across that full temperature range. This guarantee is documented in the "Typical Application" section of the LT1499HS#PBF datasheet and confirmed by production test limits at both extremes.
Can the LT1499HS#PBF operate from a single 2.5V supply?
Yes - the LT1499HS#PBF supports single-supply operation down to 2.2V, so 2.5V is fully within specification. At 2.5V, the input common-mode range extends from V– (0V) to V+ (2.5V), and the output swings within 35mV of each rail at 0.5mA load. Gain-bandwidth reduces to 5.8MHz and slew rate to 2.2V/μs, both still sufficient for many low-voltage sensor interfaces.
How does the dual-input-stage trimming in the LT1499HS#PBF improve common-mode rejection?
The LT1499HS#PBF uses separate NPN and PNP input stages, each trimmed at opposite supply rails (NPN at V+, PNP at V–). This eliminates the typical rail-to-rail op amp CMRR degradation near V+ or V–, delivering >93dB CMRR across the entire input range. In contrast, conventional rail-to-rail op amps exhibit >20dB CMRR loss within 200mV of either rail - a key differentiator validated in the LT1499HS#PBF's CMRR vs. common-mode voltage plots.
Is the LT1499HS#PBF pin-compatible with other quad op amps in 14-pin SO packages?
No - the LT1499HS#PBF uses a non-standard pinout where Pin 4 is V+ and Pin 11 is V–, unlike industry-standard TSSOP-14 quad op amps (e.g., LM324, MCP6004) which place V+ on Pin 4 and V– on Pin 11 but assign different functions to Pins 1, 7, 8, and 14. Direct replacement requires PCB layout revision; consult the LT1499HS#PBF pin diagram before substitution.
