LMH6503MTX

Instrumentation, Op Amps, Buffer Amps Overview

The LMH6503MTX is a wideband, low-power linear variable gain amplifier manufactured by Texas Instruments. It features a single channel with a slew rate of 1.8 kV/us and an input bias current of 20 uA. The device operates within a supply voltage range of 5 V to 12 V and supports an operating temperature range from -40 C to +85 C. Key electrical parameters include an input voltage noise density of 6.6 nV/sqrt Hz, a maximum voltage gain of 70 dB, and a unity gain configuration of 1 V/V. It is housed in a TSSOP-14 package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the complete part number including suffixes such as NOPB against official Texas Instruments documentation to ensure correct specifications and compliance. Confirm packaging details, specifically that the MTX suffix indicates reel packaging, and validate lead times directly with authorized distributors or the manufacturer. Ensure environmental certifications match project requirements before finalizing procurement orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a linear-in-voltage gain profile is required rather than linear-in-dB. Consider the 135 MHz bandwidth and 70 dB gain range for applications demanding precise amplitude control. Evaluate the TSSOP-14 package constraints against PCB layout limitations. Compare power consumption figures against system budget requirements relative to alternative amplifiers in the LMH series.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the LMH6503 series of wideband amplifiers. It is distinct from similar parts like the LMH6502 which offers linear-in-dB gain characteristics. The LMH6503 is designed to provide consistent voltage gain linearity across its operational range, making it suitable for specific analog signal processing tasks where voltage proportionality is critical.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check for LMH6503MAX/NOPB if SOIC packaging is preferred over TSSOP. Verify functional compatibility with LMH6503MT if different suffix variations exist in inventory.
