Key Features
- Radiation hardness assured (RHA) qualification enables reliable use in space, satellite, and high-radiation industrial environments
- Ultra-low input bias current of 10 pA typical at 25°C and 0.4 nA maximum over temperature preserves accuracy in high-impedance sensor circuits
- Rail-to-rail input and output (RRIO) with 85 dB minimum CMRR maximizes dynamic range on wide supply rails from a single package
- Quad op-amp configuration (4 amplifiers per package) reduces component count and board area in multi-channel precision signal conditioning designs
Applications
LMP7704HBH/EM is designed for precision signal conditioning in space-qualified instrumentation, satellite payloads, and radiation-tolerant industrial systems where low input bias current and stable offset are critical over wide temperature excursions. Its RHA qualification and RRIO architecture make it suitable for charge amplifiers, photodetector transimpedance stages, and data acquisition front ends where even picoamp-level leakage degrades measurement accuracy. Multi-channel designs such as strain gauge arrays, precision DAC output buffers, and active filter banks benefit from the quad configuration that keeps four matched amplifiers within a single compact package.

Frequently Asked Questions
How does the LMP7704HBH/EM achieve 10 pA input bias current, and which sensor interface designs benefit most?
The LMP7704HBH/EM uses a precision CMOS input stage to achieve a typical input bias current of 10 pA at 25°C and a maximum of 0.4 nA over the full operating temperature range. This makes it ideal for photodiode transimpedance amplifiers, pH electrode buffers, and electrometer inputs where even nanoamp bias currents would create millivolt-level offset errors across megaohm source impedances.
What radiation tolerance does the LMP7704HBH/EM carry, and how does it compare to commercial-grade alternatives for satellite designs?
The LMP7704HBH/EM is radiation hardness assured (RHA), meaning it has been tested and guaranteed to maintain specified performance up to a defined total ionizing dose (TID) level in a space radiation environment. Commercial-grade op-amps without RHA qualification may degrade after exposure to doses as low as 10 krad(Si), while RHA devices like the LMP7704HBH/EM are screened to survive far higher doses, making them mandatory for LEO and GEO satellite analog front ends.
What is the common-mode rejection ratio of the LMP7704HBH/EM, and why does it matter for differential sensor measurements?
The LMP7704HBH/EM specifies a minimum CMRR of 85 dB with a typical value of 130 dB. In a bridge sensor measurement at 5 V supply, 85 dB CMRR limits common-mode error to less than 28 µV for a 5 V common-mode swing, which is well below the 260 µV input offset voltage maximum and ensures that power supply noise does not corrupt millivolt-level differential signals from strain gauges or thermocouples.
For a 4-channel precision data acquisition front end, how does using the LMP7704HBH/EM reduce BOM compared to using four single op-amps?
The LMP7704HBH/EM integrates 4 matched op-amps in a single package, replacing four individual devices. Each channel shares a common precision process to minimize channel-to-channel offset mismatch, and the single package eliminates 3 additional device footprints plus their associated decoupling capacitors. In radiation-tolerant designs, qualified components are often cost drivers, so integrating 4 channels in one RHA device can significantly reduce both part count and procurement complexity.
