Product details
Overview
LTC6910-2HTS8#TRMPBF from Analog Devices is a digitally programmable gain amplifier (PGA) with inverting architecture, rail-to-rail output, and 3-bit digital gain control selecting gains of 0, 1, 2, 4, 8, 16, 32, or 64 V/V. It operates from single or dual supplies (2.7V to 10.5V), delivers 11MHz gain-bandwidth product at G=64, features 8nV/√Hz input voltage noise density at G=1, and supports high-precision signal conditioning in harsh industrial environments up to +125°C.
For engineers reviewing the LTC6910-2HTS8#TRMPBF datasheet, LTC6910-2HTS8#TRMPBF pinout, LTC6910-2HTS8#TRMPBF application, or LTC6910-2HTS8#TRMPBF equivalent, key selection criteria include guaranteed operation over –40°C to +125°C, precise low-noise gain stepping for sensor front-ends, rail-to-rail input/output swing under varying supply conditions, and compatibility with 3.3V/5V logic-level digital control inputs.
Technical Context
The LTC6910-2HTS8#TRMPBF implements an inverting amplifier topology with internal op-amp core and precision resistor network controlled by three digital inputs (G2/G1/G0). Its half-supply AGND reference enables true single-supply operation without external biasing, while rail-to-rail output stage ensures full dynamic range utilization across supply voltages from 2.7V to 10.5V.
Gain accuracy is maintained across temperature via laser-trimmed resistors, with typical gain error ≤ ±0.1 dB at G=1 and ≤ ±0.25 dB at G=64 (VS = 5V, RL = 10kΩ). The device exhibits 11MHz gain-bandwidth product at G=64 and maintains >55dB CMRR and >60dB PSRR across its operating range, supporting stable performance in noisy industrial signal chains.

FAQ
What is the maximum operating temperature for the LTC6910-2HTS8#TRMPBF?
The LTC6910-2HTS8#TRMPBF is rated for continuous operation from –40°C to +125°C, with all electrical specifications guaranteed across this extended industrial temperature range. This H-grade qualification makes the LTC6910-2HTS8#TRMPBF suitable for under-hood automotive, motor drive feedback, and high-temperature industrial control applications where standard commercial or industrial grade parts would fail.
How does the AGND pin function in the LTC6910-2HTS8#TRMPBF?
The AGND pin of the LTC6910-2HTS8#TRMPBF provides an internally generated reference voltage equal to approximately VS/2, enabling true single-supply operation without external bias networks. It features a 5kΩ internal resistance and can be overdriven by an external system analog ground reference near mid-supply, allowing flexible integration into existing bias architectures while maintaining rail-to-rail input capability at unity gain.
What gain settings does the LTC6910-2HTS8#TRMPBF support?
The LTC6910-2HTS8#TRMPBF supports eight discrete inverting gain settings: 0, 1, 2, 4, 8, 16, 32, and 64 V/V, selected via the 3-bit digital input combination (G2/G1/G0). Unlike the LTC6910-1 or LTC6910-3 variants, the LTC6910-2HTS8#TRMPBF uses binary doubling progression optimized for wide-dynamic-range applications such as automatic ranging and programmable instrumentation amplifiers.
Is the LTC6910-2HTS8#TRMPBF pin-compatible with other members of the LTC6910 family?
Yes, the LTC6910-2HTS8#TRMPBF shares identical pinout, package (8-lead TSOT-23), and terminal functions with the LTC6910-1 and LTC6910-3 variants. However, gain tables differ: LTC6910-2HTS8#TRMPBF provides binary-doubling gains (1, 2, 4, 8…), while LTC6910-1 offers decade-like steps (1, 2, 5, 10…) and LTC6910-3 delivers linear increments (1–7). System-level compatibility requires verifying gain code mapping in firmware.
What is the gain-bandwidth product of the LTC6910-2HTS8#TRMPBF at maximum gain?
At G=64, the LTC6910-2HTS8#TRMPBF delivers a guaranteed minimum gain-bandwidth product of 11 MHz (typical 13 MHz), defining the –3dB bandwidth limit for high-gain signal paths. This specification ensures usable bandwidth up to ~172 kHz at G=64, supporting accurate amplification of ultrasonic sensor outputs, motor current harmonics, and other mid-frequency industrial signals without phase distortion.
