Product details
Overview
LTC6910-1HTS8#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, 5, 10, 20, 50, or 100 V/V. It operates from 2.7V to 10.5V single or dual supplies, delivers 11MHz gain-bandwidth product, and achieves input voltage noise as low as 8nV/√Hz at gain = 1 - used in precision data acquisition front-ends where dynamic range up to 120dB is required.
For engineers reviewing the LTC6910-1HTS8#TRMPBF datasheet, LTC6910-1HTS8#TRMPBF pinout, LTC6910-1HTS8#TRMPBF application, or LTC6910-1HTS8#TRMPBF equivalent, key selection criteria include guaranteed H-grade operation to +125°C, precise gain accuracy across temperature, rail-to-rail input/output swing compatibility with single-supply systems, and internal AGND reference generation for simplified biasing.
Technical Context
The LTC6910-1HTS8#TRMPBF implements an inverting amplifier topology with a digitally controlled feedback network. Its 3-bit parallel interface (G2/G1/G0) sets discrete gain states without requiring external resistors or calibration. The internal op amp features rail-to-rail output stage and supports unity-gain stable operation with rail-to-rail input signals when configured for G = 1.
It integrates an on-chip half-supply reference at the AGND pin (5kΩ source impedance), enabling single-supply operation without external bias networks. Gain accuracy is maintained across supply voltages (2.7V–10.5V) and over the full –40°C to +125°C operating range, with offset voltage drift limited to 6µV/°C and gain error ≤ ±0.1dB at G = 10 under typical conditions.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable gain amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC6910-1ITS8#TRPBF | Same functionality and pinout, but rated for –40°C to +85°C only; lower max junction temperature (125°C vs 150°C) | Suitable for commercial/industrial indoor applications without extended thermal requirements | Select when full H-grade temperature range is unnecessary and cost optimization is prioritized |
| AD8251ARMZ | 4-channel, SPI-controlled PGA with 10MHz GBW, 20nV/√Hz noise, and 100dB CMRR; requires external clock and SPI interface | Better suited for multi-channel synchronized acquisition or systems with existing SPI infrastructure | Choose when higher channel density, serial control, or superior CMRR is needed - at expense of added interface complexity |
Compared with LTC6910-1ITS8#TRPBF, the LTC6910-1HTS8#TRMPBF provides guaranteed performance at +125°C ambient, essential for automotive and industrial edge nodes; versus AD8251ARMZ, it offers simpler parallel control and lower noise at G = 1, but lacks multi-channel integration and serial configurability.

FAQ
What is the maximum operating temperature for the LTC6910-1HTS8#TRMPBF?
The LTC6910-1HTS8#TRMPBF is specified for continuous operation from –40°C to +125°C ambient temperature, with a maximum junction temperature of 150°C. This H-grade qualification makes it suitable for under-hood automotive applications and high-temperature industrial environments where standard I-grade (–40°C to +85°C) devices would require derating or thermal mitigation.
Does the LTC6910-1HTS8#TRMPBF require external resistors to set gain?
No, the LTC6910-1HTS8#TRMPBF does not require external resistors to set gain. Its 3-bit digital inputs (G2/G1/G0) directly select one of eight factory-trimmed gain values (0, 1, 2, 5, 10, 20, 50, or 100 V/V) using an internal switched-resistor network. This eliminates gain-setting errors, layout sensitivity, and BOM additions associated with discrete resistor networks.
Can the LTC6910-1HTS8#TRMPBF operate from a single 3.3V supply?
Yes, the LTC6910-1HTS8#TRMPBF operates from a single 3.3V supply (within its 2.7V–10.5V range). Its rail-to-rail output and internal AGND reference enable full-swing signal processing without external bias circuitry. At 3.3V, the AGND pin settles to ~1.65V, supporting true single-supply operation for sensors and ADCs referenced to the same supply.
What is the input voltage noise of the LTC6910-1HTS8#TRMPBF at gain = 10?
The LTC6910-1HTS8#TRMPBF exhibits 9.4nV/√Hz input voltage noise density at gain = 10 (measured at f = 50kHz). This value is confirmed in the Electrical Characteristics table on page 7 of the datasheet and remains stable across temperature and supply voltage variations, supporting high-fidelity amplification in medium-gain sensor interfaces.
How is the AGND pin used in single-supply configurations of the LTC6910-1HTS8#TRMPBF?
In single-supply configurations, the AGND pin of the LTC6910-1HTS8#TRMPBF provides an internally generated half-supply reference (e.g., 2.5V at VS = 5V) with 5kΩ source impedance. It serves as the common-mode reference for the inverting amplifier, enabling rail-to-rail input operation. For improved PSRR, a 1µF bypass capacitor is recommended between AGND and ground.
